El Oso Loco Trail Races Series

Embark on a unique trail running experience with the El Oso Loco Trail Races Series, a vibrant mid-week event designed to showcase the stunning trails of the Bear River Range in Utah's Uinta-Wasatch-Cache National Forest. On June 10, 2026, join fellow enthusiasts in Logan, UT, for a challenging and scenic adventure. This particular race date offers two distinct distances: a 9.6-mile long course and a 5-mile short course. More than just a race, El Oso Loco, meaning "The Crazy Bear," fosters community and supports the Cache Trails Alliance's Adopt-a-Trail program, with all proceeds benefiting trail maintenance and resources for local users.

The June 10th event at Right Hand Fork promises a memorable journey through Cache Valley's scenic backyard. The 9.6-mile long course, known as the Willow to Cottonwood Loop, features a significant elevation gain of 1,735 feet, while the 5-mile short course, the Willow Creek Out n Back, still provides a stout climb of 895 feet. Runners should be prepared for a self-supported experience on the course, as there are no aid stations along the route; participants are required to carry their own water and fuel, though water will be available at the start and finish lines.

What truly sets the El Oso Loco Trail Races Series apart is its commitment to the local trail running community, offering an invigorating evening challenge. Races for the long course typically begin at 6:30 PM, with the short course following at 6:45 PM. This series, capped at 125 runners per race date, is crafted as a two-month fitness program, encouraging participants to enhance their speed, discover new trails, and forge new friendships. Typical race day conditions in early June in Logan, UT, bring comfortable highs around 78°F and lows near 47°F, with only a 5% chance of precipitation, providing ideal weather for a spirited trail run.
