Summary (adapted from Race Website): Rolling single track trails within McDowell Mountain Regional Park in Fountain Hills, AZ and a traverse of the McDowell Mountain Range within the City of Scottsdale’s McDowell Sonoran Preserve. 50 Mile runners will run the 50k loop plus a lollipop and out and back section, seeing the Maricopa Trail heading North towards Brown’s Ranch and climbing to the top of Thompson Peak!

Lessons Learned from Race Reports

  • Remember the park charges a $6 park entry fee per vehicle
  • With several races going on at once, make sure you know which ribbon color marks the course you should be on (50M = white)
  • It will be cold at the start of the race, especially before the sun comes up, so plan accordingly for what you wear pre-race and to start
  • Single track trail is very runnable in many sections of the course
  • Easy to go out fast with the beginning part of the race being relatively easy, rolling, runnable trail
  • Exposed trail – it will get warm and bring sunscreen!
  • The descent from Bell Pass (~mile 28) is more technical switchbacks until you hit Thompson Peak Road, which is ~ 1 mile
  • Be ready for one last little hill before getting to the start/finish aid station heading into mile 42
