Ironman 70.3 Erkner 2026

IRONMAN 70.3 Erkner is a middle-distance triathlon held in Erkner, near Berlin, during a September race weekend. The primary event involves a swim in Dämeritzsee, followed by a bike course along the Spree, and concludes with a run through Erkner. The weekend also features shorter races, including the 5i50 Erkner Triathlon and the 4:18:4 Triathlon, offering alternatives to the 70.3 distance. The event attracts an international field despite its size: recent editions have seen over 3,000 triathletes from more than 70 countries, with participants from Trinidad and Tobago, Iceland, Japan, and India among them. The event also caters to families, not solely adult endurance athletes, as IRONKIDS engages hundreds of young participants, and a Family Party at the sport center provides games and activities throughout the weekend.
