Long-course racing is won between the workouts. Your AI coach scales volume intelligently, protects recovery, and rehearses the race-day plan — so you arrive sharp and finish strong.


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.
Your training load and freshness drive every session. Burnout is the silent PB killer.
Nutrition, pacing, and taper rehearsed — race day feels familiar, not scary.
Inside your plan
Your plan adapts as you train based on what you actually did and how you're feeling — 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, schedules a deload when you need one, and keeps your other quality sessions 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 week you get a pacing strategy, hydration plan and fuelling timeline based on your fitness and race distance. 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, schedule, race date, and how you're feeling.
Every detail taken care of
Base, build, peak, race blocks — locked to your race date.
Saturday rides build intelligently towards race distance, not randomly.
Bike-to-run combos so race-day legs aren't a surprise.
Carbs/hour and sodium targets practised in training, not on race day.
Two short sessions a week that carry you through the long block.
Training tuned to your declared terrain and your real fitness.
Train for your 70.3
Each race plan tunes your training to your declared course terrain.

"Relatively new to triathlon but experienced with TrainingPeaks, Garmin and Strava. Transition has genuinely impressed me. 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."
