AI Running Coach
Your AI running coach. Always available, always adapting.
PRYSM uses real-time performance data to act as your personal running coach — building plans, reading recovery signals, and recalibrating your training after every session.
Not a chatbot. A training engine.
Most AI tools for runners give you generic advice or one-shot plans. PRYSM goes further: it builds a personalized training program from your biometric data, adjusts it after every session, and models your fatigue to protect you from overtraining. It doesn't answer questions — it does the work.
How the PRYSM coaching engine works
Connect your data
Sync your Garmin, Apple Health, Coros, or Suunto. The coaching engine reads your pace, heart rate, and recovery metrics from day one — no manual setup.
Define your goal
Distance, target time, race date, weekly availability. PRYSM builds a training program from your actual capabilities — not an assumed baseline.
Train. The engine coaches in real time.
After each session, PRYSM cross-references your RPE and biometrics to calibrate the next workout. It spots overtraining risk before you feel it.
What makes PRYSM different from other AI coaching tools
Data-driven, not advice-driven
PRYSM doesn't suggest workouts. It generates them from your performance history and modifies them in real time based on how your body actually responds.
Fatigue modeling, not just logging
The fatigue engine tracks accumulated training stress and flags recovery needs proactively — before breakdown, not after a bad session reveals the problem.
Marathon and race preparation built in
The same adaptive engine that runs your daily training also manages your peak timing, long run progression, and taper for any goal race distance.
Works with the data you already have
No new hardware required. Connect your existing watch and the engine starts learning from your training history immediately.
Questions about the AI coaching engine
What runners ask before starting with PRYSM.
A human coach checks in periodically and adjusts your plan based on your reports. PRYSM recalibrates after every single session — using biometric data and RPE to make decisions in real time, 24/7. It's not a replacement for expert coaching; it's always-on plan intelligence.
