What If · Race Strategy Simulator

Your Race.
Rewritten.

Adjust power, rest stops, and night pacing. The simulator uses your actual MMP curve, speed-power relationship, and decoupling data to project exactly how each change would affect your finish time — and what it would cost physiologically.

Move the sliders to simulate a different race strategy.

Power strategy · actual vs simulated
How your power output would change across the race under the new strategy.
HR trajectory prediction
Projected heart rate drift. Harder first half = steeper HR rise in the second.
Speed over race · actual vs projected
Predicted average speed by race third under each strategy.
Power-duration curve · where you can push
Your MMP curve from this race. The horizontal line shows the simulated intensity — anything below is sustainable, above risks depletion.

The psychological model uses your actual race decoupling, VI, and night riding data.

🔥 Burnout Risk Assessment
—

Burnout risk is computed from TSS load, W' depletion, cardiac drift, and rest adequacy.
