Link Garmin in a single form. We pull 18 months of activities, sleep, HRV, and recovery in the background while you finish setup. Whoop, Coros, and Apple Watch are coming soon.
Paste the connector URL + credentials into Claude — web, desktop, or Claude Code — and the coach is just there. No new app to learn.
Ask anything — "how am I doing this week?", "why did I fade on Sunday's long run?", "plan the next four weeks toward my race." The coach reads the underlying data, not just the labels your watch shows you, and remembers across conversations.
A sample exchange, drawn from a real ultrarunner's Garmin data. The same lens applies to cycling, hiking, ski touring, and other endurance work.

"Why did I fade on Sunday's long run?"
Coach Claw
It wasn't your aerobic engine. Looking at the splits, your HR stayed pinned at 152–156 for the full 18 mi — that's the same HR you held for 13 mi the previous Sunday at the same pace. What changed is the cadence collapse: you dropped from 175 spm in miles 1–8 to 162 spm in miles 13–18, and vertical oscillation climbed from 8.4 to 9.2 cm. That's neuromuscular fatigue, not cardiovascular.
Probable cause is fueling. You're past hour 2:30 in this one, and your weekly carb intake on long runs has been ~40 g/h based on what you've told me. At that pace you'd have been net-negative on glycogen by mile 12. Bump to 70–90 g/h next time — practice it on the 12-mi midweek run first so your gut tolerates it. We've also got two months until the race; the long run progression is fine but the durability piece needs the fueling habit locked in.
One thing to watch. Your HRV dipped from 48 to 41 the night before this run after the wedding on Friday. Probably not the dominant factor here, but worth knowing — your nervous system was already mid-recovery when you started.
