Superior Spring Trail Races

The Superior Spring Trail Races, set for May 16, 2026, in scenic Lutsen, MN, offer an exhilarating challenge for trail runners across 50K, 25K, and 12.5K distances. This highly regarded event, founded in 2003, takes runners on an "extremely hilly, rugged and technical" journey along the iconic Superior Hiking Trail, traversing the majestic Sawtooth Mountain Range. Prepare for a demanding course that parallels the greatest freshwater lake in the world, Lake Superior, climbing to nearly 2000-foot peaks and revealing breathtaking vistas of the lake and dense inland boreal forests. Runners will navigate 99% single-track trail, crossing whitewater rivers and serene streams through mystic forests of birch, aspen, pine, fir, and cedar.

The 50K route boasts a significant 4,200 feet of elevation gain and loss, while even the 12.5K, a point-to-point course, presents a rugged 600 feet of ascent and descent, making it unsuitable for first-time trail runners due to its technicality and remote sections with no aid stations. The 25K and 50K races are out-and-back from the start/finish at Caribou Highlands Resort, where all distances conclude. Participants consistently praise the "relentless" yet rewarding nature of the trail, the encouraging community, and the well-organized event supported by enthusiastic volunteers. The 50K course features four aid stations stocked with a variety of provisions, ensuring support for longer distances.

Typical race day conditions in mid-May bring highs around 55°F and lows near 38°F, with an approximately 11% chance of precipitation, meaning runners should be prepared for potentially muddy and challenging terrain. Due to its immense popularity, registration for the Superior Spring Trail Races is managed through a lottery system. Beyond the personal challenge, participating in this event contributes to the preservation of these remarkable trails, as the race makes substantial annual donations to the Superior Hiking Trail Association.
