Same pattern the last 3 runs — you fade on climbs after 2 miles. Try lifting cadence 5 spm before the hill.

Want to hit that same hill again this Saturday?

HOW IT WORKS01–03

Run, write one line, get coached.

01STEP 01

Run

Just run with your Apple Watch. HealthKit pulls in distance, pace and heart rate automatically.

02STEP 02

Reflect

One condition emoji, one line. Add where it hurt, if it did. That's it.

03STEP 03

Get coached

Claude reads your history, spots the pattern, and leaves you a question for next time.

SHARPER OVER TIME1 → 20 RUNS

Ten entries in, the coaching changes.

Run one gets generic advice. Run ten gets advice that knows your hill-pace pattern. Coaching gets sharper the more you log.
