About the Thirsty 13 Half Marathon

This is the biggest half marathon in the Durango area, pulling 400 to 500 finishers to a course built for fast times. Entry comes two ways, race only or race plus a San Juan Brewfest ticket, and the finish area at Ska Brewing turns into the party either way. It draws a lot of runners attempting a first half or a personal best on the descent.

Course

The race starts at Hesperus Church near 8,000 feet, runs south on the La Plata Highway, then picks up County Road 125 for roughly four miles of steady downhill. From there it turns into Wildcat Canyon and runs past Lake Nighthorse on the way into town, losing about 1,400 feet overall. A short climb known as Ska hill in the final mile is the one place the course pushes back.

Race-day weather

Late August mornings in the La Plata Valley start cool, often in the 50s at the high point of the course. The descent runs into warmer air and strong high altitude sun, so the closing miles usually feel hotter and brighter than the start line did.
