Built for runners who want to race the course, not a generic pace chart.
PaceKit is a race-day coaching app. It runs on your iPhone and Apple Watch and talks to you during your race — mile by mile — using course-specific data and your own running history.
Most pacing apps give you a flat target and hope the course doesn't notice. PaceKit knows the hills, the aid stations, the wind, the neighborhoods where the crowds thin out. It adjusts what it says to you based on what's actually in front of you.
Because running a marathon with a generic pace strategy is how people blow up at mile 20. The course is specific. The strategy should be too.
We've spent months building a library of 112+ US race courses, each one sourced from official materials and verified by hand. That's the whole point. Anyone can build a timer. The hard part is knowing the course.
Six coaches, each with a distinct voice and personality. Scott is the hype man. Eric is the hard coach. Raul is the chill buddy. Samantha, Jordan, and Sally each bring something different. You pick the one you want in your ear.
The coaching isn't a script. It responds to how you're actually running, what's coming up on the course, and what you've told the app about yourself.
PaceKit is built by a small team in Los Angeles. We're runners ourselves. We test it on real races.
