The US Canine Biathlon REWIND is an obstacle course 5k where runners work together with their dog to navigate varying terrain and challenging obstacles like A frames and balance beams. The REWIND challenges veteran Biathlon runners with a new twist—the course is run in reverse, from the finish line to the start line. The event is a great introduction to the Biathlon format for first-time runners as well. Running with a dog is recommended, but not required.

To celebrate the Halloween weekend, the Biathlon will hold its first ever Canine Costume Contest, with prizes including kennels, fitness tracking collars, and more. The event also features camping and an afterparty with free beer for race participants (21+) and a throwback disco Monster Mash!
