Every week, Hiron builds your plan from scratch: your physiology, your phase, your calendar, your recent sessions.
Something changed mid-week? Message Hiron. The plan updates in seconds.
Open today's workout and see exactly what to do: intervals, paces, zones, and why this session matters today.
After every workout sync, Hiron writes a Coach's Take: full analysis, what went well, what to watch, and what it means for your week. All before you finished stretching.
Swim, bike and run targets built from your tested thresholds: pace, watts and a finish-time range for every leg, with the coach's brief on how to ride it. They move as your fitness moves.
Explore the elevation profile and break the bike course into sections. See how to approach the climbs, descents and the road between them.
Course profile
Ride steadily and save energy for the run.
You held a consistent effort through the final hour. A solid endurance session.
Every week closes with a review: score, hours, discipline balance, what went well and what to watch. Next week is built from it.
Optional cycle tracking, from Garmin or your own log. Hard sessions land where you're strongest, recovery where you need it. Anonymised for the coach, always optional.
Gender, age, limiter disciplines, all factored in from day one.
Real people, inside the app. The team behind Hiron trains and races, and you can message us any time.
Coco is always one click away. Licensed sports doctor from Switzerland, professional endurance coach, and athlete herself, speaks four languages.

TRIATHLETE · CO-FOUNDER · BUILT DIFFERENTLY
I qualified for 70.3 World Championships without a human coach. Not because I thought I was smarter than one, but because I couldn't find one that fit how I train, how I think, and what I could afford.
So we spent 2 years building the system we needed. That's Hiron.
It's not replacing a human coach. It's the best option when you don't have one.
HEAD COACH
A pain that won't go away. A race you're not sure your body can handle. A block of training that isn't landing the way it should. I'm always one click away.
I'm a licensed sports doctor from Switzerland, professional endurance coach, and athlete myself.
Book a consult and I will review your data, answer your questions, and tune Hiron more closely to you. You get a full human read, an AI tuning, a coach's report, and two follow-up messages.
