The 2026 Mt. Sneffels Half Marathon-10K-Kids-Fun Run returns to Ridgway, Colorado on August 15th. This event spans the scenic landscapes of Ouray and Ridgway, offering a half marathon for seasoned runners and a 10-kilometer race as well as a kids fun run. Race morning in Ridgway brings crisp early-morning air at around 7 am when temperatures hover between 10 to 28 degrees Celsius. The event takes place on firm but slightly soft trails, providing both challenge and beauty for participants. Spectators can expect sunny skies with an average of twelve hours and thirty-three minutes of sunshine that day. The Mt. Sneffels Half Marathon-10K-Kids-Fun Run has been a fixture in the Ridgway community since 2017, drawing over one hundred participants annually to support Mount Sneffels Education Foundation's initiatives. This event not only tests endurance but also strengthens local bonds and supports educational programs. The race course winds through the picturesque towns of Ouray and Ridgway on an out-and-back route for the half marathon and 10K, with a straightforward one-mile loop reserved for young racers. The start is at Ridgway's downtown park, where runners gather under tall cottonwoods before heading uphill toward Mount Sneffels and back. Elevation changes are minimal but noticeable as you climb and descend along the course, making for an engaging yet manageable route. Aid stations will be strategically placed to ensure hydration points every three kilometers on the half marathon path. Trail conditions promise to be firm with a slight softness due to recent rains, adding texture to your run. Weather-wise, expect temperatures in the high teens to mid-twenties Celsius, with humidity around 51%. This translates into comfortable but noticeable heat during direct sunlight and cooler mornings as you start out. A gentle breeze of about seven kilometers per hour is expected throughout race day, helping keep conditions pleasant for all participants.
