Join us August 5, 12, 19 & 26 for a fun series of shorter midweek trail races.

Our goal is to offer a fun, low-key series of races designed to give newer trail runners an opportunity to dip their toes into the trail racing waters, and to offer more experienced trail racers a chance to sharpen their speed on shorter, quicker courses. All races will start at 6:00pm, ranging in distance from 5k to 12k. Results will be tabulated according to chip times, with series points awarded for each race. Top series finishers will earn unique awards.

We'll have a wide selection of vintage Gnar race shirts, and all registrants are welcome to their pick to call their own.

After each race, we will be providing pizza with support from the Fort Collins Running Club and beverages with support from New Belgium Brewing.
