Free tools for ultra runners
A finish-time predictor that reads your course, a cutoff calculator that prints a pacing strip for race day, and a way to put two races side by side. You can use all three without an account.
Finish-time predictor
Reads the course
Pick your race or upload its GPX, add a recent result, and get a finish time worked out from the course, with splits and a likely range.
Aid station cutoff calculator
5 races ready
See how much time you would have in hand at every cutoff. UTMB, Western States, Hardrock, Leadville and Comrades are ready to go, or paste the cutoffs of any race.
Compare two races
Any two races in the directory
Put two courses side by side: their profiles overlaid, the climbing, how long the field takes and where the cutoffs get tight.
Cutoff calculators for specific races
The cutoffs are already filled in, with notes on where each race gets tight.
The rest of RunPact
These tools are free. The app itself builds a training plan around your race, links your Strava and Intervals.icu runs to it, and every race in the race directory has its course in 3D.
