Official event pageWhat this race demands
IRONMAN 70.3 Jönköping requires sustained management of three distinct disciplines over a standard 113 km triathlon distance, testing both raw physiological capacity and transitions.
Multisport transition capacity
Athletics must transition smoothly from a lake swim in Munksjön to a cycling leg through scenic landscapes, and finally finish with a run through the center of Jönköping.
Aerobic endurance
Covering the 113 km total distance demands high aerobic efficiency to sustain output across the swim, bike, and run without premature fatigue.
Target 60 to 90 grams of carbohydrates per hour during the race to sustain energy output over the multi-hour duration.
