Marathon and relay courses

City insight: Tucson
Tucson is the county seat of Pima County in southern Arizona and the most populated city in the county. It is the second-most populous city in Arizona after Phoenix, lying 108 miles southeast of Phoenix and 60 miles north of the United States-Mexico border, and it is home to the University of Arizona. The desert climate brings extremely hot summers, so the cooler months from October to April are the best time to race.
