Know what your next ultra will demand.
Look at every climb before you get there, see how long it will take you, and train for the course you're actually running.
You can look around without making an account.
A finish-time estimate that accounts for the climbs, the descents and your fitness instead of assuming a flat pace.
Fly the course in 3D, so the hard parts are familiar on race day.
RunPact recognises your Strava and Intervals.icu runs and links them to the sessions in your plan.
“I built this because I was tired of guessing my race-day pacing and gluing spreadsheets together.”

Training plans that adjust
Start from one of our templates, pick one shared by another runner, or set up your own phases, session types, intensity and volume. The plan is built week by week around your race date.
- Templates for flat, rolling and mountain races
- Upcoming sessions change when runs feel too easy or get missed
- Take a break for illness or injury and the plan picks up after it
Course analysis
Open a race from the directory or upload any GPX. You'll see the key climbs, a pacing plan matched to the terrain, and the whole course in 3D.
- 3D flythrough of the full course
- Pacing adjusted for every climb and descent
- Finish-time predictions from a model trained on real ultras
The race pages and the model are built from real results on courses like these, and the analysis works on any GPX you upload.
