Lessons Learned from Race Reports

  • Required to carry at least a liter of water
  • The race will take you back to the start after the finish for a small fee – be sure to sign up for it
  • Recommended you don’t leave cars at the start because of the remoteness of the area
  • Trail traverses some rocky sections with big boulders, expect to go slower
  • Be ready for heat not only with temperatures but exposure to the sun from lack of big trees for shade
  • Use stream crossings to cool off whenever possible
  • Terrain looks sandy with a lot of loose dirt – very tiring to run in and try not to fight it, or you’ll waste more energy
  • Be aware of cactus and other bushes that can scrape, sting or cut you
  • While a lot of the climbs and descents look gradual, there are some short, steep sections
  • Bring enough water between aid, especially if you tend to drink a lot of water to begin with
  • Bring your own calories with aid stations only offering water and fresh fruit
