The Nifty Fifty

About This Race

The Nifty Fifty has quietly established itself as a cornerstone of Arizona's trail running calendar over more than a decade of consistent operation. Set in the rugged terrain around Vail, this multi-distance event offers runners three distinct challenges ranging from an accessible 10K to a demanding 50K traverse through some of southern Arizona's most varied landscape. What distinguishes this race is its thoughtful course design that showcases the region's diverse trail systems. The 50K route weaves through highland terrain before descending to follow Salmon Creek, creating a journey that tests both climbing strength and technical descending skills. The race's longevity speaks to strong local organization and a course that has proven both challenging and fair to the hundreds of runners who have completed it since 2013. The August timing places this race in Arizona's monsoon season, when afternoon thunderstorms can provide both relief from heat and additional technical challenge. Early morning starts help runners tackle the most exposed sections before temperatures peak, though the 5,000 feet of elevation gain ensures this remains a serious undertaking regardless of weather conditions.
