Shell Lake Sprint Triathlon/Duathlon
The Shell Lake Sprint Triathlon/Duathlon takes place in Shell Lake, Wisconsin, on July 25, 2026, and is organized by the Shell Lake Lions Club. The event is held at the Shell Lake beach and Memorial Park beside a 2,600-acre lake and is run annually on the fourth Saturday in July.
Two primary race formats run concurrently: a traditional swim, bike and run triathlon, and a run, bike and run duathlon. Individuals and teams may enter either format, and relay entries are offered as separate relay events. Timing services are provided by Duluth Timing and Events.
Distances for each format are:
- Triathlon: 1/3 mile swim, 15 mile bike and 3.4 mile run
- Duathlon: 2 mile run, 15 mile bike and 3.4 mile run
Medals are awarded to all participants. The course route uses the public beach, lakeside park and nearby countryside, and the event setting includes a campground adjacent to the park. General entry fees are listed for individual and relay categories, and registration opens in January and closes at the end of April 2026.
