Golden Gate Dirty Thirty
Meander through groves of aspen, green meadows and thick pine forests. Get majestic views of snow-capped mountains from rocky ridges. Golden Gate consistently shows the best that Colorado has to offer. Offering a single track, single loop course, the Dirty Thirty is the perfect course for both experienced and novice ultra runners. Started in 2009, the Dirty Thirty has continued to grow and has developed into a one of the premier ultra-events in the Denver area.
