XTERRA McDowell Mountain features a 15-mile long course for the more endurance oriented runners which winds out Pemberton Trail and climbs up towards Dixie Mine. Don’t forget to check out the cholla forests and fields of beaver tail cacti. The shorter 7k course is, well, scenic. I mean, the trail is called the Scenic Trail. Following a counterclockwise loop, this rocky trail will keep you on your toes.
