From the Organizer
Imagine a triathlon that begins just steps from a sparkling 2,600-acre lake, surrounded by the charm of a small town where life moves at a more peaceful pace. The Shell Lake Lions Triathlon/Duathlon, held annually on the fourth Saturday in July, brings athletes and spectators together for a memorable race through one of Wisconsin’s most scenic communities. With a course that winds along the beautiful countryside, a public beach, lakeside park, and campground, participants enjoy more than just a physical challenge—they experience the warmth and creativity of Shell Lake itself.
The Shell Lake Lions Club hosts two events at 8 AM on Saturday, July 25th, 2026 at the Shell Lake beach. Timing services are provided by Duluth Timing and Events. There are 2 events, the triathlon (a traditional swim/bike/run) and the duathlon (a run/bike/run event). Both events will run concurrently. Individual or teams may enter either event.
The triathlon course is a 1/3 mile swim, a 15 mile bike and 3.4 mile run.
The duathlon is a 2 mile run instead of the swim, a 15 mile bike and 3.4 mile run.
Medals will be given to all participants.

About These Sports
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Triathlon
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think. Three sports in one race means three movements to train and race day never gets monotonous.
Duathlon
Run, bike, run. The multi-sport format without the swim. Two disciplines, one race — a great bridge between running and triathlon.
