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.
