Seasonal Running in Arizona

Arizona has the longest winter running season in the country — October through March in Phoenix delivers highs of 65-80°F under cloudless skies. Summer is a different story: Phoenix regularly hits 110°F+ and pavement temperatures can reach 160°F. Flagstaff at 7,000 feet stays 25-30°F cooler than the valley and offers four-season running with snowy winters.

Running Culture in Arizona

Phoenix's winter running scene is thriving, with the Rock 'n' Roll Arizona Marathon and Mesa Marathon drawing snowbirds and locals alike. Flagstaff has become an elite altitude training hub, with multiple professional running groups based there. The McDowell Mountain trails in Scottsdale offer desert singletrack year-round.
