Training readiness for ultrarunners
Know you're ready for race day.
Ultra Readiness turns your Garmin training and recovery data into an honest picture of how prepared you are for your target ultra — no vibes, no guesswork, just the signals that matter over long distances.

How it works
01
Set your target race
Distance, date and terrain. Everything is measured against the race you're actually training for — a flat 50K and a mountainous 100-miler demand different preparation.
02
Bring your training data
Upload FIT files straight off your Garmin — distance, elevation and heart rate import automatically — or log runs manually. Full account sync, including daily recovery data like sleep and HRV, arrives with our Garmin Connect Developer Program access.
03
Watch readiness build
A transparent model scores your volume, long-run progression, back-to-backs, vert and recovery trends against your race — and flags what needs attention while there's still time to fix it.
Signals that matter over ultra distances
Generic training apps score you for a 10K. Ultra Readiness watches the things that decide whether a long day in the hills goes well.
- Weekly volume and long-run progression
- Back-to-back long days and cumulative vert
- Acute:chronic training load
- HRV and sleep trends — absorbing well, or showing strain
- Race simulations: terrain, fuelling, heat and fatigue notes
- Time-to-race context on every signal
Your data, on your terms
- Health data is only collected with your explicit consent, and you can withdraw it at any time by disconnecting Garmin.
- No advertising, no analytics trackers, and your data is never sold.
- Ask and your account and data are deleted.
