South Sourdough Trailhead, 115 Co Rd 116, Nederland, CO 80466, USA

About the Event

The race is intended to be a difficult and fun free of charge backcountry event; any and all plans can change due to trail conditions for the runner’s safety.  Snowshoes will be required unless the race director chooses to change the requirements due to trail conditions.  All racers are required to carry 20 ounces of liquid and 600 calories of nutrition. Be Safe and Leave No Trace.

Race start/finish at the South Sourdough Trailhead near the University of Colorado Mountain Research Station off the Peak to Peak Highway CO 72 on County Road 116. Race begins at 8:30 am.

Racers begin from the South Sourdough Trailhead parking lot (start line) head north on the trail to Brainard Lake Road.  There, the 18K racers will turn around at Brainard Lake Road and return to the South Sourdough Trailhead (finish line).  The 30K racers will continue across Brainard Lake Road following the Sourdough Trail loop and returning back to Brainard Lake Road and then on to the South Sourdough Trailhead (finish line). Note: if you are running the 30K, the cutoff to Brainard Lake Rd is 11:30 AM. If you reach there after 11:30 AM please turn around with the 18K runners. This is for safety. There is not cell service out here, it's cold and it gets dark fast. We want everyone back at the Start/Finish in time. You will not be disqualified, you will just be listed as a 18K runner instead of a 30K runner for finishing times. 

There will be an aid station at the Brainard Lake turnaround. It will have hot tea and granola bars. That's it.

There is, at best, spotty cell phone service in Nederland. Please put the address to the trailhead into your direction-finder before you leave in the morning so you will know where to find us. ​
