Hiron is an AI-powered training coach for triathletes and runners. Instead of a static PDF plan, you get a living season: every week is planned around your races, your available hours, and what you actually did last week. YOUR SEASON, PLANNED END TO END Tell Hiron your races and goals, and it builds a periodized season — base, build, peak, taper — week by week, all the way to race day. A PLAN THAT ADAPTS EVERY WEEK Complete your sessions, fill in a short weekly check-in, and Hiron adjusts the next week: more load when you are absorbing training well, recovery when you need it. WORKS WITH YOUR DEVICES Connect Garmin, Wahoo, Polar, Hammerhead Karoo or Strava and your completed activities flow in automatically. Garmin and Wahoo users also get structured workouts sent straight to their device. Every integration is optional. APPLE WATCH Record sessions on your wrist with step-by-step guidance and haptic pace cues that tell you when to speed up or slow down. No phone needed during the workout. RECORD ANY WORKOUT Record a free workout on your iPhone, even one that is not in your plan. Hiron matches it to your sessions and asks before linking an uncertain match. APPLE HEALTH Connect Apple Health and Hiron reads your workouts, routes, heart rate, power, sleep, HRV and resting heart rate to track recovery and adapt your plan. Access is read-only and optional; Hiron never writes to Apple Health. EVERY SESSION ANALYZED After each workout you get a clear breakdown: how you executed each segment, heart-rate zones, pacing, pool swim sets, and a coach's take on what it means for your training. STRENGTH AND MOBILITY Illustrated strength sessions built around your season, plus optional mobility work when your body needs it. ASK YOUR COACH ANYTHING Chat with Hiron about your plan, your fatigue, or a session you want to move — and the plan updates accordingly. Every answer is clearly labelled as AI-generated. Built for triathlon (swim, bike, run and strength) and for running-only seasons alike. Hiron's training suggestions are not medical advice. Consult a physician before starting a new training program.
