Train smarter for your next IRONMAN or 70.3 with an AI coach that manages volume, periodisation, and race-specific preparation — personalised to your fitness, schedule, and target race.
IRONMAN training requires careful volume progression over months. The AI tracks your training load and helps prevent the overtraining that derails so many IRONMAN preparations.
Your plan follows proven periodisation models — base, build, peak, taper — with each phase calibrated to your race date and current fitness level.
Training adapts to your target course — open-water swim practice, terrain-matched bike work, and run sessions that mirror race-day demands.
Progressive open-water swim training with technique drills and threshold work.
Build sustained power for 112 or 56 miles with structured intervals and long rides.
Develop the run fitness to hold pace after hours of swimming and cycling.
Race-specific bike-to-run transitions that prepare your legs for race day.
Dial in your race-day fuelling with structured nutrition rehearsals during training.
Arrive at the start line fresh and confident with an optimised taper protocol.
Training for a specific race? Each race page has course-specific training tips tailored to the swim, bike, and run conditions.

"Transition has made my training simple and dynamic. With changing schedules and weather, this system adapts to the variables and helps me improve every day."
Creed Hendrickson
Triathlete
"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."
Simon Wilkins
Triathlete
"I get a full three-sport plan that adjusts to my starting fitness and my ongoing training, provides immediate feedback on workouts, can adjust plans quickly based on my progress or schedule interruptions, and can even provide strength, flexibility, and nutrition advice. It all comes at a small price compared to a human coach."
Prescott Balch
Triathlete
"A really well-crafted app for multisport athletes. The developer acts quickly on suggestions. Highly recommend."
Matteo Castagna

"Transition has helped me improve my IRONMAN training more than any other method I’ve come across in my triathlon journey. It’s incredibly precise and personalised. I can’t recommend it highly enough!"
Carlos Rebelo

"A great option for beginners who don’t want to spend $300/mo on a pro coach but still want comprehensive, adaptive, structured training with basic feedback and a few tips."

Yes. Transition’s AI coach creates personalised IRONMAN training plans that adapt to your fitness level, schedule, and target race. The AI manages training volume, periodisation, recovery, and race-specific preparation — the same principles a human coach applies, but available 24/7 and adjusting in real time based on your data.
A human coach typically costs $200–500/month and works on a weekly check-in schedule. Transition’s AI coach costs $19/month and adjusts your plan daily based on your actual training data, recovery metrics, and schedule changes. You get the same periodisation science and race-specific preparation, with faster feedback loops and more personalised day-to-day adjustments.
Transition supports all triathlon distances: Sprint, Olympic, IRONMAN 70.3, and full IRONMAN 140.6. Each distance has specialised training approaches — from high-intensity work for sprints to the endurance-focused volume management needed for full IRONMAN preparation.
The AI monitors your training load, fatigue, and recovery metrics to progressively build volume while helping prevent overtraining. It schedules strategic deload weeks, manages the balance between high-volume endurance work and quality sessions, and adjusts your plan when life gets in the way — exactly what a good IRONMAN coach does.
