About Theron Triathlon Training Plan
Get triathlon-fit without overdoing it. Theron is your adaptive triathlon coach. It builds a structured swim, bike, run and strength plan around your real week, paces it to what your body can actually handle, and sends every session straight to your Apple Watch or Garmin. Six in ten self-coached triathletes get hurt training for a race, usually from doing too much, too soon. Theron watches how fast your training is ramping up and eases off before that happens, the same way a real coach would. TRAINS YOU AT A PACE YOUR BODY CAN HANDLE Your plan tracks how quickly your training load is climbing week to week and pulls back before you tip into overtraining. Recovery data from Apple Health (HRV, sleep, resting heart rate) decides how hard today should be. If you are fatigued, Theron gives you an easier session. FITS YOUR ACTUAL LIFE Set the days and hours you can train. Missed a swim because work ran late? Your schedule restructures itself automatically, with no double-counting and no scramble to catch up. FOUR DISCIPLINES, ONE PLAN Swim, bike, run and strength, balanced together as one structured plan instead of four separate to-do lists. Brick sessions included, so race day is not the first time you run off the bike. TEACHES YOU THE SPORT AS IT COACHES YOU Theron's Take, the built-in AI coach, explains what today's session is for and why, in plain language. Terms are explained the first time you meet them, so you finish a season knowing how training actually works, not just what you were told to do. GROWS WITH YOU First Sprint or fifth Ironman, it is the same coach. Fully periodized plans, base, build, peak and taper, that peak you exactly on race day. FIND YOUR RACE Search the race catalog by franchise (Ironman, T100, Challenge, Xterra and more), by distance (Sprint, Olympic, 70.3, T100 or Full), and by continent, or add any custom race. Theron supports every distance: Sprint, Olympic, Half-Marathon, Marathon, 70.3 and Full Ironman. BUILT FOR YOUR WATCH, NOT JUST SYNCED TO IT One-tap export: send a full structured workout (swim, bike, run or brick) to Apple Watch, Garmin, Wahoo or Zwift in a single tap. Live guided workouts: follow the session and your effort zones on your wrist, tracked through Apple Health, Garmin, Coros or Strava. Connected everywhere: Apple Health, Apple Watch, Garmin, Coros, Wahoo, Strava and Zwift. SEE WHERE YOU STAND Theron Score benchmarks your swim, bike and run fitness out of 100. Your readiness chart shows fitness, fatigue and freshness over time, so you always know whether to push or rest. BUILT ON REAL SPORTS SCIENCE Training protocols are based on peer-reviewed sports science, with proper periodization and a taper that peaks you on race day. Real endurance, built the way coaches build it, explained the way a beginner needs it. RIGHT FOR YOUR FIRST RACE, STILL RIGHT IN YEAR THREE Whether it is your first Sprint or an Ironman, Theron gives you structure without spreadsheets. No PDF plans, no guesswork, and nothing you need a sports-science degree to read. Start with 30 days of personalized, adaptive coaching, free. Terms of Use (EULA): https://theron.app/terms/
What’s new
Version 1.0.32 · Updated October 15, 2026
This update brings a weekly check-in, Apple Watch workouts that match your set, and kit tips for outdoor sessions. • Weekly check-in: on Today, review last week’s sessions, load, and streak, then set the week ahead, with an easier restart after illness, injury, or a break • What to wear: outdoor sessions suggest kit from feels-like temperature and wind, down to long or short bike pants, and ask for your location if the weather looks off • Zones from your workouts: setup estimates your swim, bike, and run thresholds and heart rate from workouts you already did; edit any of them, and bike waits if those rides have no power • Swim titles match the set: swim workout names and notes now describe the intervals you actually swim • Heart rate from your data: Theron can suggest a new max or resting heart rate from recent daily logs, the same way it suggests a new FTP • Trainer power from your Watch: indoor rides recorded on Apple Watch use the raw power samples, so the chart matches your trainer, not the interval summary • Watch workouts match the set: Apple Watch swims and runs now include the rest between intervals, and pace swims alert on pace, not heart rate
