From goal time to finish line: race day on RunPact

Pick a finish time on any of our 33 race pages and you now get your checkpoint times, a sheet for your crew, a tracker that keeps working without signal and a live link your crew can follow. The 3D flythrough was rebuilt too, right down to the weather on race day.

Training for it: steadier plans, a race-first dashboard and RunPact on your phone

Training plans now run on one block rhythm with a lighter week at the end of every block, the dashboard starts from your race, and RunPact installs on your phone and shows your plan without signal.

33 ultras by the numbers, and you can fly every one of them

We turned our race results corpus into public pages: finish-time distributions, aid station cutoff pressure, and segment-by-segment field pace from 28,350 real finishers across nine countries. Every page ships with a 3D flythrough of the course.

Quieter, sharper: what else shipped this summer

Race pages got the headlines, but the app changed more. A guided plan builder that doesn't make you back-navigate, a training week that stopped shouting, activity matching that now covers Intervals.icu, and a 3D flythrough that knows which race it's flying.

A flat 50k and a trail 50k are not the same race

Two runners. Same distance. Same goal time. Wildly different races. If your training doesn't account for the terrain you're actually running on, you're preparing for the wrong event.

Six plan templates, built around real ultra races

Not every ultra is the same race, and not every plan should be the same plan. RunPact now ships with six purpose-built training templates, each one a different blueprint for a different kind of ultra.

Training plans built for ultrarunners (not adapted from road running)

There's no TrainerRoad for ultrarunners. Most plan generators assume flat roads and marathon distances. We built something different, and it's just getting started.

How RunPact predicts your race time (without AI hype)

In an era where AI has become a buzzword, we want to be transparent about what actually powers RunPact's race time predictions. Spoiler: it's not a large language model, and it doesn't use any trendy AI techniques you're probably thinking of.
