Runners are allowed to run with a pacer from Hancock (mile 49) onward, and we’d highly recommend them for the section between Hancock and Monarch Pass. Pick you pacers wisely, this is a tough race and it’s not a great place for first time pacers. Experienced pacers will be a big advantage, so chose wisely. Be sure to read the details below, they should cover everything regarding pacers. If you’re not seeing something, check the Runner’s Guide first, then email the RD if you still can’t find what you’re looking for.


How to pick up a pacer bib

To get a pacer bib, pacers will need to go to one of the locations listed below and present a COSAR Card and Photo ID, and sign a waiver. Pacers' can pick up a bib and sign a waiver at any of the following locations:

  • Packet pickup

  • Race start

  • Hancock Aid Station

  • Monarch Pass Aid Station

  • Blanks Cabin Aid Station

General Pacer Rules

  • Pacers are allowed from Hancock AS to the Finish.

  • Runners over the age of 65 may have a pacer from the start.

  • Only one pacer per runner is allowed, with the exception of the final 3.5 miles where multiple pacers are allowed.

  • Pacers must wear a bib at all times.

  • Pacers must carry the required gear at all times.

  • Pacers cannot be picked up or dropped off at non-crew accessible aid stations.

  • No muling - pacers cannot carry things for the runner.

  • Pacers cannot have drop bags, but may use their runner’s bag.

  • Pacers must check in and out of all aid stations with their runners (“Runner ## and pacer are out/in!” for example).



Runners are allowed the use of a crew during the race, but we give the same caveat as we did with pacers - this is not a good race for new crews. The aid stations are hard to get to, there’s virtually no cell phone service, and many of the drives between aid stations are over 2 hours. While crews are very useful, they pose a difficulty to the organization of the event. Several aid stations have very limited parking, and some require walking 1/4-1/2 of a mile to reach. If you do wish to use a crew, please be sure to be thoroughly prepared. Full crew details are available in the Crew Manual and Runner’s Guide, this is simply an overview. Study up!

Basic driving directions are available in the runners guide. A more detailed manual (including maps and pictures) will be available in June.
