IRONMAN Erkner
IRONMAN 70.3 Erkner sits just outside Berlin on 13 September 2026: a 1.9 km swim in the Dämeritzsee, 90 km on flat Brandenburg roads, and a 21.1 km run through the town.
Brandenburg is lake and pine forest, and the bike course reflects it. Flat, sheltered in places and exposed in others, and fast if you can hold an aero position for the full 90 km. There is no terrain to force a recovery, which is precisely why people over-ride the first half here.
The lake is small and shallow. Mid-September will have taken the edge off it, but it can sit close to the wetsuit cut-off in either direction, so bring both options and decide on the day.
The practical advantage is Berlin. Erkner is on the S-Bahn from the city centre, so you can stay somewhere with actual restaurants and treat the trip as a weekend rather than a logistics exercise.
