Race Rules + Gear

Know the Rules!

Recommended Gear

We suggest you carry the following gear. You will be in remote wilderness, and you are responsible for your safety. If you are injured it may be several hours before we can reach you, so you need to be prepared. Do not think it will not happen to you! Weather changes quickly in the mountains, and every year we have racers that DNF due to environmental conditions, so prepare accordingly. You may elect to carry additional gear, like bear spray, at your discretion.

  1. Headlamp (after 8:00pm)
  2. Full water bottles or hydration pack to carry 2L of fluid
  3. Wind/water resistant jacket
  4. Toque or warm hat
  5. Sun hat
  6. Whistle (for alerting others)
  7. Space blanket (shelter)
  8. Bear spray or bear banger (IF you know how to use it)
  9. Race Bib (mandatory)
  10. Timing Chip (mandatory)

If you do not wear your timing chip or bib number, as per the race rules, you are not considered a competitor in the event.

No cups at aid stations

Note: We do not supply disposable cups at our aid stations, so you must have a vessel if you want water or electrolyte. You are welcome to refill bottles and bags.

**We do not encourage teammates to run together as it is meant to be one person per leg, however, we recognize that teammates often run together in order to show support to young or new runners. The runner designated for that leg is the one who must run the entirety of that leg. For safety reasons, Race Administration must be aware that additional runners are on that stage of the race.
