How the prediction works
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 291 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 automatically or sent.
The app adds predictions from your training log (Strava), race-day pacing and more. Free, no sign-up.

Points to consider for this course
- The overall time limit allows about 20:52/km including stops. This average does not guarantee meeting intermediate cutoffs.
- No intermediate points are recorded, so the longest gap is not calculated. Check the official aid list for fueling intervals.
- The profile is missing or estimated. Check the official course map for climb locations and steep sections.
These are simple calculations and observations from recorded information, not personal finish probabilities or difficulty ratings.
