The Dirty Turtle 25/50k is a challenging, technical trail race with lots of vertical and singletrack. The race is hosted by the Evergreen Turtle Rockets. 

The course will be 75% singletrack and 25% dirt/gravel service roads, with over 7k of elevation gain. There are several steep climbs, including “Your Mom,” and a climb of 1000ft in a mile up to "Turtle Rock", where there will be some mild class II scrambling as you mutter curse words to yourself. The 50k route was slightly modified due to timber harvesting, but don’t fret....we added some gnarly climbing and primitive trails! You’ll still enjoy the summit of Green Mountain, and the views of both Cascade and Olympic mountain ranges. Come out and kick off your Summer trail race season with us!
