How it works

From a folder of old runs to direction you can train on.

01
Upload your history

Connect Strava or drop in your files — years of runs welcome.

02
We read it

Zones and current fitness set from what you've actually run.

03
Train with direction

Every session has a purpose — and gets scored against it.

Current fitness

Zones set from your real running. Confirmed by hand.

Not %maxHR guesses. Each zone is observed in your last 28 days — pace and pulse together — then confirmed by a coach who's raced at 2:09.

Current performance profile proof cards

Performance profile

Fitness proven by recent efforts. Never stale.

Your 1k to 15k profile is built from proof — real efforts inside the last four weeks. Every proof carries an expiry, so your profile never claims a fitness you no longer hold.

Coach read

Every session, scored against its purpose.

You didn't just run 14.1 km — you ran Aerobic Power. After every upload, RunZones checks the work you did against the work the session was for, and tells you plainly how it landed.

Training calendar

Your weeks, coloured by zone.

Every run lands on the calendar as a zone-coloured dot — recovery to VO₂ max — with proof sessions flagged where they happen. The shape of a week, at a glance.

Race recipe

See the recipe behind your best racing — and what's missing now.

RunZones finds the mix of work that led into your best blocks — volume, zones, long-run durability — and compares it with what you're doing today.

The coach

“I read files the way I'd review a professional athlete's.”

Every Performance Review is read by me, not a model. I look at your zones, your proof, your recipe — and write back what a coach would say if you were on my squad. Read an example review →
