CPKM PaceKit
AI Running Race Coach
Only for iPhone
Free · Designed for iPhone
iPhone
AI coaching via headphones w/ elevation + water stations + pacing, live GPS, heart rate zones, fans can track & message you mid-run. Free for Love Run Philly.
PaceKit is a race-day copilot that coaches you through your AirPods in real time. We meticulously build each course into our system so the AI knows every hill, water station, and elevation change. Built by a runner who needed it mid-race, we now service 100+ running events across the U.S., with more being added weekly.
HOW IT WORKS
1. Start PaceKit at the starting line.
2. Put in your headphones.
3. Run. We've got the rest.
Your AI coach knows the course elevation, your goal time, and your current pace. It tells you when to push, when to hold back, and when a hill is coming so you can prepare instead of react. It knows when a slow split is smart pacing on a climb. You can even speak back to the AI to ask race-specific questions, give it instructions, and record notes mid-run.
Six AI voices to choose from - from a gruff buff man to a chipper British woman.
SPECTATOR MESSAGING
Share a link before the race. Your fans get live GPS tracking with real pace, heart rate, and mile splits - not the race's 5K checkpoint updates. They can type a message and it gets read aloud through your headphones mid-run. One-tap emoji cheers for quick-send that appears instantly on your device.
COURSE-AWARE INTELLIGENCE
PaceKit doesn't give generic advice. It's loaded with actual GPX elevation data from your specific race. It knows the climb at mile 8 before you're there. It knows when there's a water station ahead. It builds your pacing strategy around what the course actually looks like, down to a T, and helps get you through it, on your time.
