The race timer, station workouts and training plan built only for fitness racing. Every leg on your wrist, every split on your phone, and a plan that takes you from today to the start line.
Free. No account. No ads. Your data stays on your devices.
A 1 km run, then a station, eight times over. The watch knows the order, the distances and the loads for your division, so all you do is tap when you move on.
Loads follow the official standards for Open and Pro, men and women. Switch division once; the watch follows.
Elapsed time, this leg, heart rate and calories at a glance. A projected finish that updates with every split. One big button to move on, and an undo if you tapped early.
Time one station. Run into it, the way the race does. Or work and rest on a countdown with haptic cues, so you never look at the screen mid-set.
Station, then straight into a run. The rest between them shrinks as race day gets closer, because fresh legs are not what you race on.
Half or full race at 40 to 100 percent load, rounded to real plates and bags. Start it from the phone, run it on the watch.
Runs, stations with the day's load, rests and time caps. Save it, sync it, start it with one tap.
Tell it when you race, which division, how your week looks and what you bring to it. It writes every week from base to taper, puts today's session on your watch, and ticks it off when you finish.
Eight by Eight · 8 runs · 8 stationsEvery leg as a bar, your heart rate drawn over the top, the fastest station and run called out, and a medal when you beat your best. Made on your phone, shared wherever you like.
Every rule in the generator comes from published research or the coaching practice behind the sport. The sources are in the app, one tap away.
The 8 km of running takes over half of a typical finish, so every plan keeps two to four runs a week.
Brandt et al. 2025 ↗Volume drops 40 to 60 percent over the last two weeks while intensity stays. That is what the evidence says improves race-day performance.
Bosquet et al. 2007 ↗No single session's running exceeds your longest recent run by more than 10 percent. Big single-session jumps are what predict injury.
Frandsen et al. 2025, BJSM ↗
No account. No server. No analytics. Sessions live on your watch and phone and in Apple Health, nowhere else. We never see them, and nobody else does either.
