Bear Lake Brawl Triathlon

Prepare for an exhilarating challenge at the Bear Lake Brawl Triathlon, set against the stunning backdrop of Saint Charles, Idaho, on September 19, 2026. Often dubbed the "Caribbean of the Rockies" for its breathtakingly blue waters, Bear Lake offers a picturesque yet demanding course for athletes across various distances. This multi-sport event, organized by On Hill Events, caters to a wide range of abilities, offering Sprint and Olympic Triathlons, a Half (70.3) Triathlon, and several Aquabike, Duathlon, and Aquathlon options, alongside standalone Marathon, 51.2K, 14.3M run, and 2.4M swim-only events. The challenging high-altitude setting, around 6,000 feet above sea level, adds an extra dimension to the race, even for seasoned competitors.

The swim takes place in Bear Lake's famously blue, often cold, waters, where wetsuits are highly recommended. Past participants have noted that conditions can vary, sometimes presenting with significant chop and swell, living up to the "Brawl" name. The bike courses, which include routes circling the lake or out-and-back segments, are generally described as scenic with "rollers" on the east side, offering spectacular views of the lake and surrounding mountains. While the Olympic distance bike leg does not feature aid stations, the Half distances provide ample support with water, Powerade, and bathrooms. The run segments, primarily along Cisco Road, offer flat to rolling terrain with consistent aid stations stocked with gels, granola bars, candy, fruit, water, and electrolytes. Typical race day conditions in mid-September often bring comfortable highs around 70°F and lows near 39°F, with a low chance of precipitation.

The Bear Lake Brawl Triathlon has gained a reputation for its unique combination of natural beauty and athletic rigor. While some older reviews mention past logistical challenges, more recent experiences highlight good organization and support, even attracting professional athletes in previous years. The event's diverse offerings, including the Half Aquabike (57.2M), Full Aquabike (114.4M), Half Aquathlon (14.3M), and Full Duathlon (138.2M), ensure there's a challenge suitable for nearly every multi-sport enthusiast looking for a late-season race in a truly memorable location.
