Long-course racing is won between the workouts. Your AI coach scales volume smartly, protects recovery, and rehearses the race-day plan — so you arrive sharp and finish strong.
As seen on
Progressive long rides and bricks — never more than your body and life can absorb.
Built into your week so you absorb the block instead of breaking down halfway through.
HRV, sleep, and freshness drive every session. Burnout is the silent PR killer.
Nutrition, pacing, and taper rehearsed — race day feels familiar, not scary.
Inside your plan
Your plan reshapes every week based on what you actually did, how you slept, and how you felt — not a fixed PDF written months ago.
A 70.3 demands real hours — but more hours alone don't make you faster. The AI builds progressive long days, drops a deload when you need one, and keeps your other quality intact.
The marathon-pace run after a 90-km bike is what makes 70.3 hard. Brick workouts every week train your legs to keep moving when the bike says stop.
On race morning you get a pacing strategy, hydration plan, and fueling timeline based on the course profile, weather, and your numbers. No more "I'll go by feel" — feel lies at km 60.
A week with your AI coach
A mid-block week ~12 weeks out from race day. Yours adapts to your fitness and schedule.
Yours will look different — the AI picks every session based on your fitness, sleep, schedule, and race date.
Every detail handled
Base, build, peak, race blocks — locked to your race date.
Saturday rides build smartly toward race distance, not randomly.
Bike-to-run combos so race-day legs aren't a surprise.
Carbs/hour and sodium targets practiced in training, not on race day.
Two short sessions a week that hold up through the long block.
Pacing tuned to elevation, expected weather, and your real fitness.
Train for your 70.3
Each race plan tunes pacing to the course profile and expected conditions.

The Smart Coach is good and the adaptive training seems well thought out, the app is clean and intuitive and the built in nutrition logging – especially protein tracking – is excellent."
