  • Runnable grades
  • Well-stocked aid stations placed roughly every 4 miles
  • Finisher awards
  • High quality podium awards
  • Looped course
  • A small out & back on the back portion of the course begins the race (a bit repetitive)
  • Roads can be dusty due to shared use with OHVs
  • Marathon runners take off 30 mins after 50k runners, making the placements difficult to determine at times

This run is truly beautiful. It's a push up the pass but the downhill all the way to the finish is amazing. Community is always so supportive and cheerful.
