The Colossal Vail 50/50, presented by Fleet Feet Sports-Tucson, is a combined 50 kilometer/50 mile event using a beautiful high desert section of the Arizona Trail east of Tucson, Arizona, near the community of Vail. The fast and fun course, and the support along the way, was designed by experienced members of the Tucson Trail Runners to give new ultra runners the best chances of completion, while giving experienced runners a good day as well. We gave awards to the top three male and female finishers in each event in 2014, 2015, and 2016. Every finisher gets to pick out their unique laser engraved memento. We used black Mexican river rocks in 2015 and 2016. Because the course is two out and back segments, 50 mile runners can complete the 50K route, then get finisher’s credit for that event and an award, if they choose not to complete the full 50M.
