IRONMAN 70.3 Leipzig is a half-distance triathlon — 1.9 km lake swim, 90 km flat bike through the Leipzig lake district and a 21.1 km run past the historic Sportforum. It closes the IRONMAN Pro Series season, so the pro field races alongside age-groupers.
What this race demands
This half-distance triathlon demands sustained effort across a 1.9 km swim, a flat 90 km bike leg and a 21.1 km run. Athletes need to pace the bike so they can maintain their effort on the run.
Sustained pacing
The 90 km bike leg is described as flat, favoring steady power over climbing efforts. Pacing it well matters because the 21.1 km run follows the bike.
Multisport endurance
The 1.9 km swim, 90 km bike and 21.1 km run require endurance across three disciplines and the ability to keep moving through each leg.
Run durability
The half-marathon comes after the swim and bike, so athletes must be able to sustain their running effort while already fatigued.
For a race likely to last more than 2.5 hours, plan to take in about 60–90 g of carbohydrate per hour, adjusted to what you have practiced tolerating.
