TrailMath

TrailMath answers trail-running questions from its own race catalogue and engine instead of guesses.

• Course facts for published trail races: distance, elevation, checkpoints with crew and drop-bag access, cutoff times when the organiser has published them for the coming edition, the largest climbs and the latest results summary.
• Finish-time estimates from one past race result or a UTMB/ITRA index, as a range with the model's limits.
• A fixed aid-station roadbook example that shows how segment times are laid out.
• An anonymous sample of a training plan for a race: the first two weeks in full and the season outline, built by TrailMath's training engine from a few answers (race, date, weekly running time, hours available, training days, background, terrain, timezone).
• When the runner asks to continue in TrailMath, a link that carries those answers into TrailMath's setup. Nothing is applied until they sign up or log in and tap Import, and they review every answer first.

No account and no sign-in. TrailMath covers a limited catalogue: when it has no data for a race it says so. Estimates are ranges, not guarantees, and the plan sample is not medical advice. English and French.
