- ✓ Sessions sent to your Garmin watch or exported as FIT/TCX
- ✓ Completion suggested automatically from your Strava and Garmin activities
A coach that actually reads your sessions
The AI Coach reviews your latest runs, how you felt and your morning rituals, then tells you what matters: what to keep, what to ease off, and why. When life gets in the way, it replans your next two weeks.
- ✓ Personalised coach advice on every session
- ✓ Replanning after a missed session or blocked days
- ✓ Morning check-in: fitness, sleep and energy taken into account
Track your fitness, not just your mileage
Fatigue (ATL), base fitness (CTL), freshness (TSB): your fitness dashboard tells you every day where you stand, and whether it's time to push or to recover.

- ✓ Trends over 30, 60, 90 or 180 days
