This Sunday, plan ahead before leaving home. The Rock ‘N’ Roll Arizona marathon starts Friday, with the main race occurring on Sunday.
The full 26.2-mile marathon begins at Arizona Center in downtown Phoenix and ends near Tempe Town Lake.
The full marathon race, the half marathon and the 5K, will cause many temporary closures across Valley streets and freeways.
