For trail & ultra runners
An AI coach that reads your real runs, plans your season, routes every session from your own door — and puts the workout and the route on your watch.
You run. We handle the rest. · Free while in beta · Apple Watch, Garmin and Suunto

The coach
Tell most apps you're injured and they'll happily reschedule your hardest session onto it. Tell Peak Days, and the coach weighs your body first, then makes the change, with a condition attached.

Routes
Every session comes with terrain-matched route suggestions — the distance you need, the climb the workout asks for, and as much singletrack as your area allows. Pick one and it's on your plan, your calendar and your watch.

On your wrist
Peak Days has its own Apple Watch app, and its own two apps in the Garmin Connect IQ store. Tomorrow's session arrives on your wrist by itself — the workout steps, the target zones, and the route on a trail map. A buzz at every change of step. No phone needed on the run, no files to move before it.

After the run
When you finish, you get a short, plain read of the run: was it as easy as planned, why the fourth kilometre was slow, and what it adds to your season. Per-km splits, honest heart-rate zones, and a plan that counts it done — without you touching anything.
the post-run read: verdict, numbers, map and the written analysis
The morning read
Every morning: one verdict, with the reasons shown. Your resting heart rate, heart-rate variability and sleep — each judged against your own normal range, never a global average. If your body disagrees with the plan, the coach offers the swap before you've laced up.

The coach, the plan, the morning read and routes-from-your-door work the same whichever row you are on. More about watches.
Also in the app
Search a catalogue of trail races, pick the one you're training for, and the plan builds backwards from its date, its distance and its climb.
Warm-up, work, recovery, repeats — by time or by distance, with a pace or a heart-rate zone to hold. It reaches your watch like any other session.
English, French, German, Dutch and Spanish — the app and the coach both. It follows your phone unless you choose otherwise.
Five voices, from calm guide to sharp pro. The advice is identical in every one; only the tone changes.
Vertical gain read from the watch's barometer, not guessed from the map, then broken down climb by climb after the run.
Why this exists
"I'm 40, with a family and a busy job. I had a plan in one app, routes in another, recovery in a third — and none of them talked to my watch. So I built the one place that connects it. Focus on the run, not the administration."
It started on my own Apple Watch Ultra, so I could leave the phone at home and still be reachable for my family.
Open beta
Peak Days is in beta on both platforms and free while we build. Pair an Apple Watch, a Garmin or a Suunto and every run gets guidance, the map and your route on your wrist. A phone on its own works too: plans, routes and phone-tracked runs.
iPhone: open the TestFlight link on your phone, install TestFlight, get Peak Days.
Android: the beta runs as a closed test on Google Play, so we add you by hand — email us and we send you the link to join.
