Ruffner Mt. Crusher Ridge (5k, 21K, and 42K)

This is a challenging 21K loop with a double-loop option for a 42K. Consisting of mostly single track trail, the loop will take you to every corner of the park and showcase all three of the rock crushers that give the race its name. Trails are technical and incorporate 4,500' of elevation change across the single 21K loop. The 5k route will give folks a taste of what the mountain has to offer but with a lot less elevation. Course will be well marked with sprinkler flags, survey tape and signage at turns. Runners may switch between the 21k and 42k distances at any time before or during the race by notifying race officials.

This is a 100% charitable race. All proceeds from the 21k and 42k race entry fees will go to Ruffner Mountain Nature Preserve to help them continue the great work they do. All proceeds from the 5k race entry fees will go to the Exceptional Foundation as a thank you for making the race medals for the last 2 years. Because this race is for charity, we do not issue refunds. If you cannot make it, consider it a donation to this amazing nature preserve.

Aid Stations: There will be an aid station at the start/finish, at Salvage Rd and at Gray Fox Gap (you go through this aid station twice). Aid stations will have water, Tailwind, gels and other basic ultra aid station fare. NOTE: please bring a handheld or hydration pack. October in Alabama tends to get warm in the afternoon. You will NEED hydration between aid stations.

Food: We will have the grill going at the finish. Please hang out after you finish your race and have a burger, chips, cookies, and a beverage. Vegetarian/vegan options will be available. One of the local breweries will be providing beer for the festivities. Families are welcome to eat as well!
