A 140.6 is six to ten months of work. Done wrong, it ruins you; done right, it changes you. Your AI coach scales volume intelligently, protects recovery, and rehearses every mile of race day.


Build the aerobic engine and durability that 140.6 demands — block by block, never random.
Base, build, peak, race. The AI works backwards from your race date and protects every key block.
Training load and freshness tracked daily. The AI backs off before you dig yourself into a hole.
Two short sessions a week and load ceilings built into your week — durability for the long block.
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 PDF plan you wrote in January is fiction by April. Your AI coach reads what you did each week and rewrites the next — so the plan is always honest, always relevant.

The athletes who finish strong rehearse race day for weeks beforehand. Your plan includes long-day fuelling, brick days, and progressive race-pace simulations.

Nutrition, taper, mental game, recovery — the unglamorous details are where finish times are made. The app handles them so you don’t have to remember.

A week with your AI coach
A mid-build week, 12–14 weeks out. Yours will look very different in base vs peak — the AI sequences it for you.
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 — locked to your race date, never fiction.
Saturday rides build to 5–6 hours with race-pace blocks built in.
Carbs, sodium and hydration guidance, rehearsed inside your long sessions.
Two short sessions a week — built to stand up to 30+ weeks of training.
When your training load and freshness signal fatigue, the AI reins you in before you crack.
Taper, pacing, fuelling, warm-up, mental cues — all delivered in race week.

"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."
