  • First Aid is available at all aid stations.
  • Special drinks, pretzels, bananas, oranges, PB&J, boiled potatoes and surprises!
  • Restroom facilities are varied.
  • Most have a phone, warm blankets and friendly people. Others may be miserable and lonely.
  • Thank the volunteers; they’ve been standing there since dawn or earlier.

Drop Bags (50M, 50K) Please, no black garbage bags, too easy to get put in trash!

  • Drop Bag locations
    • Hell – 22.7 miles, 50K & 50M – After the multiple River Styx crossings.
    • The Farm – 40.1 and 43.7 miles, 50M – After possible crappy muddy area.
  • Desireables but no valuables as we are not responsible for lost stuff. Ideas are shoes, socks, special food, Vaseline, scripture, TP and Head Goat Voodoo Doll.
  • AT START: Identify Drop Bag with your name & number or other identifiers. Deliver Drop Bag to the designated “Drop Bag Depot”.
  • AT EXCHANGE: Locate in Live Drop Bag Depot. When done and ready for shipment to finish, place in DROP DEAD BAG zone, (This has nothing to do with your mother-in-law!)  It will be taken to the finish. If not in Drop Dead zone, delivery could be delayed or require self-pickup at Aid Station.
  • AT FINISH: Dead bags and flashlights located in the Drop Dead Bag returned area.

Light Drop

  • Flashlights – Headlights: Recommended as 6:15 a.m. start is very dark. The tech reflective markers look like rodents shining tiny flashlights back at you, but you need a light.
  • Light drop is at the second aid station (Hell Creek Ranch.) Place in Drop Dead Zone for return to finish line. Identify yours.
