PaceBrain

Your AI running coach. Get a training plan that adapts to how your week actually went, a race-time prediction you can trust, and a daily read on whether to push.

PaceBrain is an AI running coach. It writes your training plan, adapts it when life gets in the way, and tells you what your data actually means.

Built for self-coached runners who want the thinking of a coach without the price of one.

YOUR PLAN, WRITTEN AND ADAPTED • A full training plan built around your goal race, your history and your available days • Change it in plain English — "I'm away next week", "make Tuesday easier" — and the plan re-optimises around it • Going away? Set your dates and the plan reshapes itself, including a sensible ramp back • Send planned sessions straight to your Garmin or Wahoo device

KNOW YOUR RACE TIME • Six prediction models combined and weighted to your training context • Always shown as a confidence range, never a single false-precision number • Race planner with pacing, splits and a weather read for the day • Post-race analysis of how you actually executed it

A DAILY READ ON YOUR TRAINING • RunSignal: a straight answer on whether today is a push day or an easy one • Training load tracking that flags when you are ramping too fast • Heart rate zones, cadence, elevation and pace trends over time • Your Running DNA — the profile of what kind of runner you actually are

FUEL IT PROPERLY • Nutrition and meal plans built around your training volume and preferences • Dietary preferences and foods to avoid respected throughout • Export to PDF or spreadsheet

BRING YOUR OWN DATA • Sync with Garmin, Strava, Polar and Wahoo • Or upload GPX, FIT and TCX files from anywhere else • Your whole history in one place, however you recorded it

KEEP SHOWING UP • The Climb turns consistency into altitude — every day you run earns height • Capped at four days a week, so you cannot climb faster by overtraining • It never goes down. A bad week costs you progress, never your progress so far

RUN WITH OTHERS • Leaderboards and monthly challenges • Crews for training with friends • Personal records tracked automatically

FREE FOREVER The race-time predictor is free with no signup. Premium unlocks the coaching loop — adaptive plans, insights, nutrition and analytics.
