Sunday, October 8th @ Flat Rock Ranch: Kick up your heels with the first of two Spectrum bike races presented by Chumba Cycles USA. Rawhide is the second of our trail series and takes place on one of the best trails in Texas - Flat Rock Ranch, designed specifically for mountain biking and great for running! Think: rugged, steep, and rocky - just don't think flat. Imagine the most serene of hill country ranches and top that off with racing, dancing, and relaxing under the stars. With a huge field for our start/finish, this is an ideal place to bring your family and friends to cheer you on and celebrate your accomplishment when you finish!
