A 140.6 is six to ten months of work. Done wrong it breaks you; done right it changes you. Your AI coach scales volume smartly, protects recovery, and rehearses every mile of race day.
As seen in
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 run yourself into the ground.
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.
Athletes who finish strong rehearse race day for weeks beforehand. Your plan includes long-day fueling, brick days, and progressive race-pace simulations.
Nutrition, tapering, 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 chooses 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 practised in your long sessions.
Two short sessions a week — built to hold up for 30+ weeks of training.
When your training load and freshness flag fatigue, the AI pulls you back before you crack.
Taper, pacing, fuelling, warm-up, mental cues — all delivered in race week.

"Fairly 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."
