5:30 am, before the house wakes up.
Before the school run, before the emails. The coach knows how much time you have and gives you the right session for those minutes.

Big goals.
Whatever it takes.
The coach finds a way every week, whatever work, family and life throw at you. Your group is training for the same race. ChallengeUS builds your plan from your race calendar, reads the activities, sleep and HRV your Garmin records and tells you how close you are to your goal. Every change is a suggestion: you decide.
- Connected to your Garmin
- The coach suggests, you decide
- A group for every race
REAL LIFE
Every day, one step closer to race day.
After the office, when the city slows down.
Meeting running late? The coach suggests how to move the session, and you decide.
Uphill, one hairpin at a time.
Hard weeks come at the right time, and so do recovery weeks. And you always know why.
In the cold water of early morning.
Running, cycling and swimming in one plan, built around your races.

HOW IT WORKS
Three steps, then the coach takes over.
Connect your Garmin
Activities with pace, heart rate and power, sleep, HRV and Training Readiness flow in on their own. No files, no imports: the coach always has the full picture.
Tell it your races, time and life
Main race, tune-up races, minutes available per day, work peaks. The season plan comes from advanced models: base, build, specific, taper.
Live, the plan adapts
Short sleep, a trip, a missed session? Every evening the coach re-reads everything and proposes how to change the week, with an explanation: approve with one tap, or let it decide. Sessions go to your Garmin on their own.
INSIDE THE APP
The coach for people who would never have a coach.
A coach that reads your data
Pace, heart rate, power, sleep, HRV, resting HR, Garmin Training Readiness and load: the AI coach reads them together and tells you what to do today, and why. Write to it, dictate how you feel or send it a photo.
A plan from your races, the way a coach would build it
Phases, recovery, taper and tests in the right place, long sessions that grow towards the race, never two hard days in a row. Every session with your own paces and zones, straight to your Garmin watch.
The coach proposes, you decide
A bad night, a trip, a missed workout: the coach proposes how to change the week, you see before and after and approve with one tap. The plan stays consistent with your goal and within the safety limits.
Nutrition built in
Carbs and protein per day, fuelling in long sessions, carb-loading and race-day plan: all in the same plan.
On track for your race?
Two separate indicators: how prepared you are (plan followed, load, recovery) and, for running, how realistic the time you want is. You always know where you stand versus the race.
You don't train alone
Groups hold the ChallengeUS community and a group for every race, with the people preparing it alongside you. Others only see the name you choose, never your e-mail.
AROUND YOUR LIFE
Your life changes. So does your plan.
Available
Travelling for work? Tell the coach.
Tell it where and when: it adapts the week to your days away and finds, near where you'll be, running routes, pools with lap swimming, gyms and hotels where you can train.
Coming soon
Connect your calendar.
The coach sees your meetings and trips and moves sessions to your free hours. Sessions show up in your calendar as private events, so nobody books a meeting over them.
Coming soon
Find training partners.
If you want, share your location: the coach learns your habits and suggests people preparing for the same race or training near you at the same times. Anonymous, and only with your consent.
“Coming soon” features are not in the app yet.
NEVER ALONE
Your challenge. Never alone.
In Groups you'll find people preparing for the same race as you: men and women with a job, a family and a goal as big as yours. You train in different cities and meet at the same finish line.
