What Bike Pace Calculator does
The Threshold Cycling Bike Pace Calculator estimates average speed, finish time, and target wattage for a ride by factoring in rider weight, bike weight, gradient, wind, and aerodynamic position. It outputs a detailed power dissipation breakdown showing how much effort goes to aero drag, gravity, rolling resistance, and drivetrain loss. Users can export results as shareable social cards, stem stickers, forum tables, or GPX/FIT course files for further analysis. The tool is free to use without a mandatory paid subscription. The site’s version stands out for its granular input options—specific aero position CdA values (from pro TT bars to upright commuter), a comprehensive road surface selection, and a real-time power‑dissipation chart that explains why a given speed requires a certain wattage. Compared to basic speed‑time‑distance calculators, it provides pacing guidance and a physics‑based breakdown rather than a simple calculation. Unit switching between imperial and metric is built directly into the interface.
How to use the Threshold Cycling Bike Pace Calculator
- 1
Select your rider weight, bike weight, and functional threshold power (FTP) in the Rider & Environment inputs section
- 2
Choose your aerodynamic position (e.g., Pro TT/Track, Triathlon/TT Bars, Aero Road Drops, Standard Road Drops, etc.) to set CdA
- 3
Enter the road gradient percentage, ride distance, and wind speed/direction (headwind or tailwind)
- 4
Click Calculate to view estimated speed, finish time, and a wattage breakdown by aero drag, gravity, rolling resistance, and drivetrain loss
- 5
Use the export options to share results as social cards, stem stickers, forum tables, or to ingest GPX/FIT course files
Best for
Serious cyclists and triathletes who want a physics‑based pacing estimate that accounts for position, gradient, wind, and surface, and who need shareable outputs for training plans or race strategy.
Limitations
- Results are estimates based on input assumptions; actual performance may vary
- Requires user to know their functional threshold power (FTP) for meaningful wattage targets
- Free version may include site navigation elements and commercial content alongside the calculator
