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. GARMIN SYNC Connect your Garmin account and your structured workouts land on your watch, while completed activities flow back automatically. Linking Garmin 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. Customize your workout screens on your iPhone and preview them live on the watch. APPLE HEALTH Connect Apple Health and Hiron reads your workouts, routes, heart rate, 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, and a coach's take on what it means for your training. ASK YOUR COACH ANYTHING Chat with Hiron about your plan, your fatigue, or a session you want to move — and the plan updates accordingly. KNOW YOUR RACE COURSE Upload your race GPX and get the course profile with elevation and climbs, section by section, plus a finish-time estimate based on your training. 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. ## Is Hiron safe? Not enough ratings yet to assess Hiron. ## Is Hiron legit? Hiron has limited verification signals.
