Fümmelsee Triathlon 2026

The Fümmelsee Triathlon takes place at the Natur- und Familienbad Fümmelsee in Wolfenbüttel, with the Wolfenbütteler Schwimmverein grounds serving as the race headquarters. It is a straightforward, club-organized triathlon day, featuring races for school-age athletes, youth and juniors, open-entry participants, and relay teams. The swim is one lap within the pool, the bike course follows a loop on partially closed public roads, and the run is primarily on closed paths. The start, finish, and transition area are all located on the WSV grounds, allowing spectators, families, helpers, and children to remain close to the action without extensive movement. The event's draw lies in its compact layout and the local club environment: athletes and their supporters are in proximity throughout the day, and the race offers a sense of genuine community triathlon rather than a highly produced mass participation event.
