General Questions

Best Bike Split is a app for cyclists and triathletes who race and train with power meters. The underlying technology that drives Best Bike Split lets you predict race times, plan optimal race strategy, and actually execute the perfect race plan on the big day. When we started development we had a few use cases in mind but since launching people have used the app in ways we had never initially imagined. Below are just a few use cases compiled from our members and pros.

  1. Predict future race times
  2. Plan optimal power targets for future races based on a goal Normalized Power (NP)
  3. Determine the Power needed to hit a specific time on a course
  4. Plan optimal race power targets based on a specific Training Stress Score (TSS)
  5. Pre-train a race plan indoors with TrainerRoad, Computrainer, etc.
  6. Follow power instructions during a race with our Garmin Power Files and an Edge Bike Computer
  7. Determine what equipment to use on a future race
  8. See the finish time differences of losing a few of those off season pounds
  9. Compare race plans and finish times for various scenarios
  10. Help determine aerodynamic drag without a wind tunnel
  11. Find the power needed to make the bike cut off time at Ironman

Intro to Best Bike Split

While Best Bike Split does rely on power to give an accurate model and pacing plan, it is possible to use estimated speed in lieu of power for race day execution via our Speed Based Course Cheat Sheet (which you can link to from the standard watt based cheat sheet) provided that you have done the following.

  1. Have a good understanding of what your accurate FTP (Functional Threshold Power) is based on an indoor smart trainer or from using a power meter in training (Powertap wheel).
  2. Rerun the model with the most up-to-date weather forecast update.
  3. Be flexible to know when a certain speed may be pushing your HR or level of effort too high. In these cases you can shift your target speeds down a bit and keep the same speed deltas between conditions.

Athlete, Bike & Race Setup

The first time you sign on to your account the app should walk you through the basic setup, but it is pretty straightforward and you should be up and running (rolling) in less than 5 minutes.

To create a race plan you will need to first create an athlete profile, a bike profile and either select an existing course or upload a course. Once you have these 3 items completed just click the "Add A Race" under "My Races" and fill in the race data such as course, bike, weather conditions, goal watts and power limits. If you need more information about most of these settings remember you can rollover the icon for additional information.

  1. Create your athlete profile
    • It is important to have an accurate FTP value (see below for more info on FTP)
    • Input your weight including cycling kit, helmet, and shoes
  2. Create a bike profile
    • This will estimate initial drag values for you that may need tweaking later
    • Make sure to add your complete race ready bike weight (water bottles, pedals, etc)
  3. Upload a Course or Add one from our Existing Courses
    • Course Uploads are currently limited to .GPX and .FIT (activity) files which you can export from Garmin Connect, RideWithGPS, Strava, etc. FIT files can be pulled directly off of your Garmin Device
  4. Create a Race Plan
    • Many members use their first race plan to compare to a previous race to calibrate bike drag settings
    • Try file downloads to test out training indoors, comparing plan data to actual results, or actually executing the race plan with power prompts using a Garmin Edge Computer.
    • Take a look at the cheat sheet for handy scenario based power targets.

Creating Your First Race Plan

Drag is the largest limiting factor when it comes to moving your bike forward. It is also one of the hardest factors to measure. We provide some general drag estimates based on the drop down racing and climbing position selections on your bike profile, but in an effort to help further refine an accurate drag estimate we have created an advanced Fit-Based drag calculator.

This calculator takes specific measurements about your body and position on the bike to help refine your drag profile. You can always override your final drag profile with your own calculated data from velodrome or wind tunnel test data, but the fit based calculator should give more accurate results than our standard drop downs without the costs associated with aero testing.

The following guide will help you through your measurements:

shoulder width

Shoulder Width

Width in centimeters from the edges of your shoulders while in your racing position.

hip width

Hip Width

Width in centimeters at the widest portion of your hips while standing.

hand width racing

Hand Width (Racing)

Width in centimeters of your typical hand (road) or elbow (TT/Tri) placement while racing.

hand width climbing

Hand Width (Climbing)

Width in centimeters of your typical hand (road) or elbow (TT/Tri) placement while climbing.

hip to shoulder

Hip to Shoulder

Length in centimeters from hip to top of shoulder while standing.

hip to head

Hip to Head

Length in centimeters from hip to top of helmet while standing.

seat to handlebar drop

Seat to Handlebar Drop

Length in centimeters of drop from the center of your seat to your handlebar tops or arm pads (if no drop use 0 centimeters).

torso angle racing

Torso Angle (Racing)

Angle from hip of a perpendicular line forward and a line through your shoulders in your racing position (sitting straight up is 90 degrees).

torso angle climbing

Torso Angle (Climbing)

Angle from hip of a perpendicular line forward and a line through your shoulders in your climbing position (sitting straight up is 90 degrees).

seat tube angle

Seat Tube Angle

Effective seat tube angle (Road is typically 74-76 degrees and TT/Tri is typically 78-80 degrees).

With the Time Analysis Tool (Premium Feature) it is very easy to fine tune your CdA (Drag Coefficient) using a past race or a training ride. Keep in mind that you will want to use a past race or ride in which you were on the same setup as will be used in your upcoming race and you will need to know what your average power and total bike split time was for the past race/ride.

The basic idea is to take a known course, time and average power then calculate the CdA (drag) needed to balance this equation. Here are the steps to calibrating/verifying your CdA:

  1. First you should review your Athlete Profile and your Bike Profile to ensure that they are set to match what was used on your recent race or training ride.
  2. Select or upload a course that you have already completed such as a recent race or a training ride.
  3. Set up a Race Plan using your recent race or training ride course, set the historical weather conditions for the race (for best results use the Advanced Weather (Premium Feature), then select the Normalized Power model and create your race plan.
  4. On the Race Detail page select the Time Analysis (Premium Feature) tab and adjust the power slider so that it matches your actual average power from the race/ride, then adjust the drag slider until the Adjusted Time matches your actual finish time from the race/ride.
  5. Note the Adjusted 0° Yaw CdAs shown below the Time Analysis chart.
  6. Update your Bike Profile under CdA Racing and Climbing by putting the noted CdA values from the Time Analysis Tool in the CdA field for your 0 Degree Yaw Angles. The system will automatically adjust the other yaw angles based on this initial change.
  7. To verify the adjustment to CdA, rerun the model by updating the Race Plan and check that your actual time is close to the model's predicted time. There may be a small time difference based on average power versus normalized power. You can use the Time Analysis Tool's power slider to set your average power to that of your actual average power from race day. If your CdA is correct, your Adjusted Time on the Time Analysis Tool should match up pretty close to your actual race day time without having to adjust any other sliders on the tool.

Your drag should now be calibrated and you can setup and run much more accurate power plans for future races.

Calibrating Drag With The Time Analysis Tool

This is the position that you spend the majority of a race in. Short distance triathletes and time-trialist may have an aggressive position, but most long distance athletes will be more relaxed. Here are the available race position options.

Tops

This position is mostly upright. Imagine riding your Tri or Road Bike for an easy spin.

Hoods/Bullhorns

Use this setting if you have a slight bend at your torso and your arms are roughly shoulder width apart.

Drops

This setting is reserved mostly for those racing on road bikes in short time trials where an athlete will stay in the drops. It is possible for the drag to be better in the drops than on a triathlon or time trial bike depending on the athlete.

Aerobars (Recreational Triathlete)

This setting is for those who have very little flexibility and use the aerobar more for long distance support. On a Tri Bike if your bars are at or a bit above your seat this may be a good setting for you. Consequently you could also measure your Torso Angle and if it falls in a 45+ degrees range this would be a setting to start with.

Aerobars (Midpack Triathlete)

If you are not very flexible and have a fairly upright position this is a good starting setting. If you are using clip on bars you may want to start with this setting as well.

Aerobars (Advanced Triathlete)

This would be the standard setting for the majority of triathletes and time trialists. It represents a good aero position that you would achieve if you are fairly flexible and have a proper bike fit.

Aerobars (Elite/Pro Time Trial)

Time trial specialists and small or very flexible triathletes will fit under this category. It may be very difficult to hold this position for more than a 40k race although some triathletes can hold a very tight position for races up to a half distance.

Select the condition that best fits the majority of the race course. Road condition can greatly affect drag especially over long courses. Take a look at these more detailed descriptions.

Perfect (track surface)

This should only be used if you are racing on near perfect track-like road conditions.

Good (smooth asphalt)

Good conditions would include fresh asphalt or smooth concrete roads.

Average (typical road mix)

The average setting typifies the typical road conditions observed at most triathlons or time trials. Examples include a mixture of worn concrete with minor cracks or rougher asphalt.

Poor (cracked/worn roads)

Poor road conditions include sections of considerable cracked concrete or worn down chip-seal. Roads that are not well maintained would also fall in this category.

Rough (fresh chip seal)

These roads may cause considerable bouncing up and down more than forward momentum. Fresh chip-seal or sections of cobbles may require the use of this setting.

FTP (Functional Threshold Power) represents the maximum average power you can maintain for an hour long effort. A shorter 20 min test, shown below, can be performed to approximate your FTP number.

Quick FTP Test

  • Warm Up: 15 min
  • Test: start data recording and ride as hard as you can for 20 minutes
  • Cool Down: turn off data recording and spin down for 10 min
  • Post Test: record the average power for the 20 minutes and multiply by .95 to get FTP

Uploading & Selecting Courses

Currently we only support .GPX and .FIT (activity) file types for course uploads. Course or route data can be used directly from your device as .FIT (activity) files or it can be downloaded as .GPX/.FIT files from multiple applications such as TrainingPeaks, Garmin Connect, RideWithGPS, Strava, etc. In the future we will expand to allow several file types and additional automated upload options.

Add Courses to Best Bike Split

To crop a course simply upload a GPX or FIT file like the normal upload process. Once uploaded use the elevation chart to highlight the section of the course you want to include. This will highlight the section of the course in Green on the map and move the Start and Stop icons. Save the course as normal and the cropped course will be added to your Courses page. To undo a Crop just click inside the highlighted section of the elevation chart.

course cropping

Cropping A Course

After performing analysis on an entire race course you may want to isolate certain sections or segments of a course to model individually. To do this go to the specific course page used for your model, download the GPX file, then upload that file (using the course upload button) and crop the course to the desired section. You can then duplicate your model changing out the original course for the new course section. For higher fidelity you will want to turn on the Rolling Start option in your advanced settings.

This is useful for analyzing sections of a race where you may want to test certain tactics or for training for specific sections of a course using one of our downloadable files.

To download the raw course data which includes latitude, longitude and elevation data go to My Courses, , click on the view (magnifier) icon for the course you want to download under, then click the Download GPX file button. This file is a standard course format used by most mapping and indoor trainer companies.

Note if you are using this data for training indoors it will not include any of your specific race plan power, weight or aerodynamic details. For training specifically for a course we suggest using our Erg, TrainerRoad or Zwift power files found on your specific race plan details page.

Achieving the best results from Best Bike Split is dependent on having a quality .GPX or .FIT file with accurate elevation data for our math and physics model. Below is a guide to help you select the best .GPX or .FIT data to upload to the system.

time analysis tool

Time Analysis Tool Overview

Advanced Weather Chart

The Advanced Weather chart shows a forecasted or historical weather map for the course based on both location and time. The chart shows 12 sets of forecasted/historical weather data from points along the course corresponding to the time that the athlete will be crossing into those zones. This data is pulled in from the closest weather station to the zone that the athlete is estimated to be in at that time.

Temperature

Temperature is shown in either degrees Celsius or Fahrenheit depending on your unit settings.

Humidity

Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity (which depends on the current air temperature). A reading of 100 percent relative humidity means that the air is totally saturated with water vapor.

Pressure

Barometric pressure (also known as atmospheric pressure) is the force exerted by the atmosphere at a given point. It is known as the "weight of the air". Measurement of barometric pressure is in bars, with normal pressure at sea level being 1.013 bars.

Wind Speed & Direction

Wind speed is shown in either miles per hour or kilometers per hour depending on your unit settings. The wind direction is shown in degrees and represents the direction that the wind is coming from, with true north at 0° and progressing clockwise. The graphic arrows point in the direction that the wind is going and are positioned relative to the course map, with north being at the top of the map.

advanced weather chart

Yaw Angle Distribution Chart

This chart shows you the percentage of race time you will spend in each yaw angle range based on your goal targets and weather data inputs. The yaw angle data can be used to help with race day equipment selection or can be used to support purchasing decisions. Many bikes and wheels are now designed to be faster at certain yaw angles so knowing the yaw angles you tend to experience most often in your races can help guide your major purchase decisions. To remove a data set on the chart simply click that data's label shown under the graph.

Larger yaw angles indicate crosswinds while smaller angles will be more direct head or tail winds. The general rule of thumb is to go as deep as you can from 0-12.5 degrees yaw. Above 12.5 degrees it is very athlete dependent based on the athletes ability to stay steady and in position in the crosswinds. On courses with more hills this changes a bit based on weight and speed.

yaw angle distribution chart

Gradient Chart

This chart shows you the percentage of race time you will spend in each road gradient range based on your goal targets and the terrain on the course. The gradient data can be used to help an athlete understand the nature of the course elevation. It can also be used to help highlight the type of climbs that would be beneficial to simulate in training.

gradient chart

Peak Power Chart

The Peak Power Chart shows the mean max average power values across different times for the race model. When compared to an athletes actual peak power or power duration curve this data can be used to help set any power limitations in the advanced settings section or to find areas where an athlete may need work to achieve an optimal pacing strategy for a given course. This becomes especially useful in Time Trial efforts where the peak power and the power duration curve should closely follow each other.

peak power chart

The Cheat Sheet (watts)

cheat sheetThe cheat sheet breaks the course into scenarios with power targets for each based on your goal targets and course/weather conditions. Many of our Pros and Members use the cheat sheet exclusively on race day. While racing you can follow the power targets based on the situation you are in at the time (i.e. riding into a head wind on a flat to rolling section target 200 watts or riding up a minor hill 1-2% target 215 watts).

What if I don't race with a power meter?

While Best Bike Split does rely on power to give an accurate model and pacing plan, it is possible to use estimated speed in lieu of power for race day execution via our Speed Based Course Cheat Sheet (which you can link to from the standard watt based cheat sheet) provided that you have done the following.

  1. Have a good understanding of what your accurate FTP (Functional Threshold Power) is based on an indoor smart trainer or from using a power meter in training (Powertap wheel).
  2. Rerun the model with the most up-to-date weather forecast update.
  3. Be flexible to know when a certain speed may be pushing your HR or level of effort too high. In these cases you can shift your target speeds down a bit and keep the same speed deltas between conditions.

We provide general drag setting that will work for most athletes, but you may need to do some tweaking to get your drag numbers dialed in. The best way to do this is to adjust your 0 degree yaw angle drag in your bike settings. Try finding a high and low default setting (from your bike setup) then adjust your 0 yaw drag between these points by running the model and matching your average power (not normalized) and time compared to a known race result. See "How can I calibrate my drag using a past race and the Time Analysis Tool?" above for specifics on calibrating your drag. Note you may be a bit more aero for short races where you hold your position better than longer races like Ironman where you try to stay more comfortable. We suggest creating a bike profile for each. One for longer and one for shorter distance races.

File Downloads & Device Settings

With an ever growing number of race plan files that are compatible with many Garmin devices as well as TrainerRoad, CompuTrainer, iMobileIntervals, perfPRO, PeriPedal and more it can be a little confusing on exactly which file type you need to download. Below is a brief description of each file type that we currently have available along with the devices and/or software that is compatible with that file type.

ERG Power

The ERG file contains detailed watt and time information created from your race plan which can be used with indoor training software to provide a great simulation of your race. This file type is compatible with most indoor training software including but not limited to TrainerRoad, CompuTrainer RacerMate One, PeriPedal, PerfPRO and iMobileIntervals.

MRC %FTP

Similar to the ERG file the MRC File contains detailed %FTP and time information created from your race plan which can be used with indoor training software to provide a great simulation of your race. This file type is compatible with most indoor training software including but not limited to TrainerRoad, CompuTrainer RacerMate One, PeriPedal, PerfPRO and iMobileIntervals.

Garmin Workout (Dist)

This Garmin Workout .fit file is a distance based workout file for Garmin Edge and specific Forerunner devices. When loaded* onto a Garmin device a distance based workout with watt targets corresponding to the Best Bike Split race plan is created. This workout can be used outdoors to simulate your race day efforts or indoors on a trainer in conjunction with a speed sensor and a power meter. Garmin limits workouts to a maximum of 50 steps so any plan longer than 50 segments will be intelligently combined into 50 workout steps. Garmin Workout files are compatible with Garmin Edge 500, 510, 800, 810, and 1000 cycling computers as well as Garmin Forerunner 910xt and 920xt watches.

*Garmin Workout Files must be manually added to Garmin devices in order to expand capacity to 50 steps. Please see "How do I load Garmin Power Course and TCX Power Route files on to my Garmin Device?" for details on getting the files on to your device.

Garmin Power Course

The Garmin Power Course .fit file leverages the built in courses functionality in Garmin Edge and specific Forerunner devices. This file is meant to be used while training or racing on a specific course. While riding a course on your Garmin device you will receive on-screen power target alerts as you pass latitude longitude points corresponding to your Best Bike Split race plan. Each Edge device does require some specific setup for best use of Garmin Power Courses and will require manual upload to the device. Garmin Edge 500, 510, 800, 810, and 1000 cycling computers and limited functionality is supported on the Garmin Forerunner 910xt and 920xt watches. Please see "How do I load Garmin Power Course and TCX Power Route files on to my Garmin Device?" for details best settings and on getting the files on to your specific device.

Garmin Activity

This file outputs your Best Bike Split race plan as a standard Garmin Activity .tcx file. This file can be loaded into outside software to perform additional analysis on your plan or compare your race plan to your actual race efforts. This file is compatible with TrainingPeaks, Garmin Connect, Strava, RideWithGPS, etc.

TCX Power Route

The TCX Power Route file has identical functionality to the Garmin Power Course but may not be supported by all devices. It will allow you to upload to other analysis software such as RideWithGPS to get different views of your route and power targets. Please see "How do I load Garmin Power Course and TCX Power Route files on to my Garmin Device?" for details on getting the files on to your device.

CompuTrainer Course

The CompuTrainer Course file allows you to train on the course profile for any race including the wind component you will experience. If it's a very windy race you will have to push harder on sections that would be into a headwind while experiencing the benefits of tail winds in other sections. This file is compatible with both the original 3D software as well as the RacerMate One software.

TrainerRoad (Beta)

TrainerRoad is a simple but incredible indoor training application compatible with most any indoor trainer. We have created a special TrainerRoad file that adds additional instructions and information on top of the typical ERG file functionality. This file type is in beta as we add additional features to it over the off season.

Zwift (Beta)

Zwift is a social indoor cycling video game and training platform. It allows cyclists to train and ride in a beautiful 3D environment along with other riders from anywhere on the planet. We have created a special Zwift workout file that allows athletes to load BBS Race plans as workouts into the Zwift workout library. This file type is in beta as we add additional features to it over the off season such as on screen instructions for road gradients and weather conditions.

The BBS Power Targets data field displays an athlete's race plan power targets in real time as the athlete progresses through the course. Please note that this data field will only work in conjunction with Garmin Power Course (.FIT) file.

  3. Place the .FIT file in the new files directory on your Edge 520/820/1000

For best experience use the following options:

  1. Turn your navigation settings to Direct Routing and Lock On Road to Off (found under Activity Profile / Navigation Settings)
  2. In Course Options disable Turn Guidance, disable Off Crs. Warning, disable Segments
  3. In the Specific Course Settings disable Always Display

Note: If you would like alerts when a Power Target is updated enable Course Points in this settings section. With Course Points disabled the Data Field will still update but there will not be an alert.

Riding a BBS Power Course:

  1. Select Navigation
  2. Choose your BBS Power Course file from saved courses
  3. Start your activity as you would a normal course
  4. When prompted to "Navigate to Beginning of Course?" it's best to dismiss this option (select No). As you approach the beginning of the course the head unit should find it.

If you see an N/A during a course it means your device firmware is not up to date or your device does not support the 2.2.x Connect IQ SDK. If you see No Target your course file does not contain course points.

Download the Power Targets data field from the Garmin Connect IQ store.

Garmin Power Course and TCX Power Route files allow you to load your Best Bike Split race power plans onto your Garmin devices to use during your races. When running during a race, power alerts will pop up at the bottom of your screen to indicate the proper power target based on specific latitude and longitude points along the course. Currently these files are compatible with 500/10, 800/10, and 910xt/920xt devices. These courses must be manually loaded to your Garmin device as Garmin Connect does not yet support power alerts. Instructions for loading these files are shown below:

TrainerRoad is a great indoor training tool that allows athletes to follow well thought out indoor power workouts. These workouts based on power and duration are typically called ERG (Watts vs. Time) or MRC (%FTP vs. Time) workouts. By combining your Best Bike Split race plans with indoor training provided by TrainerRoad you can start to pre train and get an accurate simulation of how it will feel on race day. We have also created a beta TrainerRoad specific file type that will be enhanced over time. Simple steps for getting race based power workouts transferred from Best Bike Split to the TrainerRoad application.

  1. First you must have a Best Bike Split and a TrainerRoad account.
  2. Create a Athlete Profile in Best Bike Split to get baseline information such as FTP.
  3. Upload a course or courses you wish to model into Best Bike Split in .GPX or .FIT format or choose one or more courses from our growing database.
  4. Create a race plan based on Goal IF, Time or TSS.
  5. From the Race Details page download the ERG, MRC, or TrainerRoad file type.
  6. Open the TrainerRoad Workout Creator.
  7. Drag the file from your downloads folder onto the left side of the Workout Creator.
  8. Name your workout in the Workout Creator and select Publish which is on the lower right.
  9. Open the TrainerRoad app and check out your BBS workout under the custom workouts.
  10. START THE RIDE!

Importing Best Bike Split Plans to TrainerRoad

Zwift is a social indoor cycling video game and training platform. It allows cyclists to train and ride in a beautiful 3D environment along with other riders from anywhere on the planet. We have created a special Zwift workout file that allows athletes to load BBS Race plans as workouts into the Zwift workout library. This file type is in beta as we add additional features to it over the off season such as on screen instructions for road gradients and weather conditions.

  1. First you must have a Best Bike Split and a Zwift account.
  2. Create a Athlete Profile in Best Bike Split to get baseline information such as FTP.
  3. Upload a course or courses you wish to model into Best Bike Split in .GPX or .FIT format or choose one or more courses from our growing database.
  4. Create a race plan based on Goal IF, Time or TSS.
  5. From the Race Details page download the Zwift file type (a .ZWO file).
  6. Place this file into your documents/zwift/workouts directory on your computer. (NOTE: Group BBS workouts in the Zwift interface by adding a new directory called BBS inside the workouts directory.)
  7. Open Zwift and your BBS workout will be available.
  8. START THE RIDE!

Coach Memberships

With a coach membership you are able to setup and/or maintain unlimited athlete profiles. Under the "My Athletes" tab you can add athlete profiles yourself or invite athletes to setup their own Best Bike Split memberships and then have them grant you access to their account.

Other than having the option to work with multiple athlete profiles, a coach membership essentially functions just like the premium athlete memberships. Once you select the athlete profile that you wish to work with, you have the ability to add/modify that athlete's profile, add/modify that athlete's bike(s), add/upload courses for that athlete and create/modify race plans.

The coach membership does have an additional link on the race details page called "Athlete Link" which is a link that you can send your client/athlete giving them access to their race detail page even without being a Best Bike Split member.
