PaceStack is an AI fitness agent that monitors your training, adapts your plan in real time, and works 24/7 — so you just show up and train.
Connects to your Strava, Garmin, or Apple Watch. Tracks every activity, sleep, and recovery signal — even when you're not using the app.
Rebuilds your training plan based on yesterday's effort, today's readiness, and your upcoming race or goal. No static programs.
Daily briefing on what to do, why, and what to watch for. Your AI coach keeps you honest — no more guessing if you should rest or push.
Reminder system, race-day prep, post-run analysis. A coach that remembers everything you forget.
Link Strava, Garmin, Apple Health, or Whoop. PaceStack reads your activity history, HRV, sleep, and load data.
A marathon in 12 weeks? First 5K? Lose 20 lbs? Tell PaceStack your target and your timeline. It builds the roadmap.
Every morning you get your session. After every run, you get feedback. The plan adjusts. You keep improving.
The average recreational athlete spends $150–$300/month on a coach — who sends a weekly plan and maybe checks in twice. PaceStack does more: daily adjustments, 24/7 monitoring, post-workout analysis, race-day strategy, and real-time feedback. All for a fraction of the cost.
This isn't a chatbot that gives generic advice. It knows your FTP, your fatigue trends, your race history, and your sleep. It makes decisions about your training every single day.
Your training should evolve with you — every day, not every 4 weeks.
