Enter your ITRA performance index to get an estimated finish time, aid-station splits and cutoff margins. This race has no finisher ITRA data, so it uses the transfer model: your predictions for the 290 races that do have finisher data, scaled by distance and elevation gain (km-effort) — the same calculation as the TRAIL STATUS app. Nothing is saved or sent.
The app adds predictions from your training log (Strava), race-day pacing and more. Free, no sign-up.
