Direct connection Free
Intervals.icu's own service, with a key you paste. It adds: Fitness, fatigue, form, ramp rate and each day's training load.
- On intervals.icu/settings, scroll to Developer Settings and copy the API key.
- In Marrow, open Connects, then Sources, then Intervals.icu. Paste the key and tap Connect.
- Marrow pulls fitness, fatigue, form and ramp rate per day, and sums each day's training load. They get their own metric pages and go on to your AI and exports.
The key stays in your phone's keychain. Sources never count toward the connect limit.
If it does not work
- Connect says Intervals.icu did not accept the key. Make a new key under Developer Settings at intervals.icu/settings and paste the whole key.
- Data from Strava is missing. Intervals.icu does not pass on activities that came from Strava, by Strava's rules. Record with a device or app that uploads to Intervals.icu directly.
