Pemberton Trail
A fast 50k and 25k run completely on trails in the beautiful McDowell Mountain Regional Park, Fountain Hills, Arizona. Gently rolling hills, great volunteers, good food, mild weather... Come on out and join us for a great day in the desert!
In 2020, Jim Walmsley smashed the previous men's 50k record of 3:11:55, set by Paul DeWitt back in 2007. Jim cut nearly 23 minutes off that time in 2020, finishing in 2:49:03. This might be the fastest course in the country, so don't miss your chance to set a PR!
