How does the simulated calculation of the racetrack work?

Our engine analyzes GPS data, route profiles, elevation profiles, and current environmental conditions. This data is combined with physical models to provide accurate predictions and simulations for any racing situation – at the push of a button for any track.

I have a GPX or TCX file – what insights does the simulation provide me?

With your file, you can conduct a realistic race time simulation based on your performance data (constant or in intervals). This provides numerous exciting insights:

  • Learn how a specific performance improvement affects your target time.
  • Find out in which areas – such as weight, aerodynamics, or rolling resistance – you can optimize most effectively.
  • Simulate different weather scenarios and recognize where wind and weather might particularly affect you.
  • Compare your simulation with real race data (when using a power meter) to uncover deviations and optimization potential.
  • Find out what the expended energy is used for.

This way, you can specifically work on your weaknesses and optimally prepare for your next race.

Does the system take wind and weather into account?

Yes. Wind direction, speed, and air density are directly incorporated into the simulation. Our models calculate, among other things, aerodynamic influences such as side forces and air resistance – depending on the wheel, track position, and weather conditions.

Do I need to install any special sensors or hardware?

No – in many cases a modern smartphone or GPS logger is sufficient. Depending on the application case, recording the trip using a GPX or TCX file including power measurement is necessary.

Does the system also work on unknown or new routes?

Yes. Our technology can capture and analyze routes through GPX or TCX files. Whether it is a known racetrack or a free route – the models automatically adapt and deliver directly actionable forecasts.

Which wheels or races are supported?

Currently, our focus is on time trial bikes. However, any bikes or races can be simulated.

What exactly does the analysis comparison tool do?

With the tool, you can load and compare multiple GPX files simultaneously – e.g. different races, laps, or riders. You get a visual analysis of speed, elevation profile, and – if available – power (Watt).

How do I calculate the rolling resistance coefficient (Crr) from power, mass, and speed?

To determine the rolling resistance coefficient Crr, you can use a simplified physical formula:

Formula:
Crr = P / (m · g · v)

  • P = Power in watts
  • m = Total mass (rider + bike) in kg
  • g = Acceleration due to gravity (9.81 m/s²)
  • v = Speed in m/s

Example:
At a power of 6,7 W, a mass of 42,8 kg and a speed of 28,8 km/h (=8.0 m/s) results in:

Crr = 6,7 / (42,8 × 9,81 × 8,0) = 0,0020

Result: Crr ≈ 0,002
This corresponds to a very low rolling resistance – typical for high-quality road bike tires on smooth asphalt or on an indoor trainer.

You can find more information and comparison values, for example, on bicyclerollingresistance.com .

How do I determine the aerodynamic drag coefficient (cwA)?

At RaceYourTrack, the determination of the aerodynamic drag coefficient (cwA) is based on the so-called Chung method. However, this requires a power meter.

Alternatively, you can use the following typical cwA values for a rough estimate:

  • Endurance / Comfort road bike: approx. 0.33 – 0.38
  • Race road bike: approx. 0.30 – 0.33
  • Aero road bike: approx. 0.27 – 0.30
  • TT / Triathlon bike: approx. 0.22 – 0.27

How does the synchronization of the plots work?

On hover over a plot, all other charts and the map are automatically synchronized. This way, you always see exactly where you are in each file – including markers along the way.

Can I zoom in on the individual plots separately?

Yes – but the system is designed so that zooming in on one plot automatically syncs all other plots and the map. This ensures a consistent comparison across all routes.

How can I remove files again?

Each loaded file will be displayed below as a button. Clicking on it will completely remove the associated route, the plot, and the marker on the map.

What happens if a file does not contain any performance data?

No problem – the performance plot will be automatically hidden then. The tool is designed to work with pure GPX files without power measurement as well.

What can I specifically use the comparison tool for?

Typical use cases are:

  • Comparison of two races on the same track
  • Analyze different performance levels or driving styles
  • Technical or material comparison (e.g. with/without trailer)
  • Performance validation during interval or training sessions.
  • Direct comparison with passengers
How does payment via Paddle work?

You can try our service free of charge for 7 days – no credit card required. After the trial period, simply choose the subscription plan that fits you best to keep full access to all features.

We use Paddle as our official payment provider (Merchant of Record). Paddle handles all payments, invoicing, and tax processing on our behalf. You can pay securely using a credit card, PayPal, or other regional payment methods.

After your purchase, you’ll receive a confirmation email and an invoice directly from Paddle. Subscriptions can be managed or canceled at any time via the link in the confirmation email or in your user account.

What happens after the trial period?

After the 7-day free trial ends, your test access expires automatically. You can then select a subscription to continue using the service – all your existing data and simulations will remain available.

Can I export or delete my data?

Yes. In your user account, you can download or permanently delete all stored data and simulations. We strictly comply with GDPR requirements.

Can I import data from Garmin or Strava?

Yes – you can import GPX, TCX, and FIT files created with devices such as Garmin, Wahoo, or Strava. Direct integrations are also planned for the future.
