IRONMAN 70.3
The IRONMAN 70.3 covers 1.9km swim, 90km bike, and 21.1km run — 70.3 miles of multi-sport endurance. It's the fastest-growing triathlon format, and the 50-59 age group is consistently among the largest at every race. Oceanside, St. George, Nice, and the 70.3 World Championship offer world-class courses. Training demands 10-15 hours per week over 16-24 weeks, balancing three disciplines with brick workouts that teach your legs to run on fatigued muscles.
