Rattler was created to feature the amazing trails of Palmer Park, one of Colorado Springs' best city parks.  Runners are treated to views of the city below and famous Pikes Peak in the distance.  While they traverse the single track, sandstone bluffs and unique rock formations rise up around them. Even though the course does not have much vertical gain, it will test runners with its technical trails. The start and finish line is located at Maizeland and Academy.  Come out and enjoy this amazing trail system, right in the heart of the city!
