COVID 19-UPDATE: Due to its very nature, the Sourdough Snowshoe Race is a small event held outdoors where most people are covered since it’s cold as sh*t. I plan on continuing this event in 2021 as long as the Sheriff office says it’s ok. As of right now we are a go and I will keep runners updated as we lead up to 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.

We are going to skip the pre-race check-in at the community center this year and do the whole check-in and bib pick up at the trailhead. Please arrive by 8:30 to pick up bib and check-in. Carpool is encouraged to the race start/finish at the Sough 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 9 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 12 PM. If you reach there after 12 PM please turn around with the 18K runners. This is an honor system, so please be safe and be smart. You will not be disqualified, you will just be listed as an 18K runner instead of a 30K runner for finishing times.

In years past there was an aid station at Brainard Lake Road, except for 2018 there was no aid station. The decision has not yet been made on whether to have an aid station here or not for the 2021 race. Check back for updates or email me at

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.
