Training that respects your rest.

Rest Day is an endurance coach that plans your season around your recovery — and re-plans it when life happens.

A training week in Rest Day: a protected rest day, threshold intervals, a long weekend ride — with planned load and hours summarized.

Sample athlete — example data, not a real person

Slept 5 hours? The plan noticed.

It reasons about your fatigue, then moves the work — not you.

Tuesday's intervals slid to Thursday; today became an easy spin. The week's purpose survives — the fatigue gets absorbed. Try it live on the sample athlete →

How it works

Step 1
Connect your training
Strava, or FIT/TCX/GPX files straight from your watch or head unit.
Step 2
Tell the coach your goal
A race with a date, or just consistency — both are real goals.
Step 3
It plans — and re-plans
A season built around your recovery, reshaped when life happens.

Why invite-only?

Rest Day is a small private beta, capped at around 25 athletes. The coach runs on real (paid) AI and I'm the one paying for it — so I grow it deliberately. Request an invite and I'll email you when a spot opens.
