What this race demands
IRONMAN 70.3 Switzerland requires sustained endurance across a 113 km triathlon featuring a swim, rolling bike course, and run in early June.
Aerobic Endurance
The 113 km total distance requires continuous cardiovascular output over several hours, demanding a well-developed aerobic base.
Bike Course Pacing
The rolling profile of the Swiss Alpine foothills requires consistent power management to maintain efficiency without depleting glycogen reserves before the run.
Run Durability
Completing the run portion, including the Stairway to Heaven feature after the bike leg, requires muscular durability and effective transition pacing.
A target intake of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the multi-hour duration of the event.
