A homegrown 100-mile loop through the southern San Juans at an average of 10,000 ft
Other trail races within 76 miles
The San Juan Softie is a 103-mile loop that starts and finishes at the Durango Nordic Center, about 30 minutes north of Durango. It circles counter-clockwise through the mountains between US 550 and CO 145, following long stretches of the Colorado Trail past Engineer Mountain, Lizard Head and the Wilson group of fourteeners. The course climbs about 19,000 ft, averages 10,282 ft of elevation and tops out at 12,438 ft, with long sections above treeline. The name is a joke: it is billed as the gentler option next to Hardrock, Ouray and High 5, but it is still a remote, rugged mountain 100 with monsoon storms, creek crossings and a 38-hour cutoff. Crew can reach only four aid stations, the first at mile 45.8, and every runner must carry a satellite tracker.

Mid-August in the southern San Juans falls in monsoon season. Mornings are usually clear and cool, but thunderstorms often build over the high country by early afternoon, bringing lightning, hail and heavy rain above treeline. Daytime highs at 10,000-12,000 ft are typically in the 50s to 60s F, while overnight temperatures can drop into the 30s F on high ground. Forecasts for Durango or Rico do not reflect conditions up high, and wildfire smoke from across the West can affect air quality in dry years.
