FREE RACE SIMULATOR

Estimate your cycling event time before you build the plan

Run a deterministic physics estimate from route distance, climbing, FTP, weight, aerodynamics and tires. No uploads, no AI call, no account required.

Assumptions

172 km curated event GPX-derived rolling route with 1800 m climbing.
75 kg rider, 9 kg bike, 240 W FTP.
hoods position, race tires, small group drafting.
Mechanical estimate only; no training history, nutrition, heat adaptation, tactics, stops or technical descending model.
Route geometry came from curated event GPX analysis stored by Ridium admins.
GPX elevation smoothing and gradient clamping are applied before physics simulation.
Weather and wind are simplified unless explicitly provided.

This is a simplified mathematical model. It is not a medical fact, diagnosis, or recommendation for weight loss or training; it only shows a mechanical simulation.
