Sierra Vista-Douglas, AZ

Sierra Vista sits at 1,400m elevation in Arizona's high desert, surrounded by the Huachuca Mountains to the east and Dragoon Mountains to the west—terrain that rewards hill runners and gravel cyclists. The Warrior Resolve 5K Series uses local military base loops and foothill routes, while cyclists tackle the Sky Island Tour, a multi-stage event that climbs into the surrounding mountain ranges and draws serious elevation gain. Summer heat is intense, but the elevation keeps temperatures manageable compared to lowland Arizona; most running and cycling happens early morning or late afternoon.
