Please do not litter on course and dispose of your trash at the aid stations.

GEAR CHECK:

We will have gear check available under the big blue registration tent. Our volunteers will have tape & markers for you to label your bag with.

PICTURES: 

You all have the best cameras in the palm of your hand. While race pictures of yesteryear were so cool, it's hard to justify the expense to our amazing photography professionals with the hope of you purchasing a race picture. Simply, it's just not worth it for us to bring folks out there. So you're on your own!!! We will have a live stream at the finish!!!

TOILETS:

Portable toilets and hand washing stations will be available in the start / finish area and at each aid station.

POST RACE:

We're at Payette Brewing in downtown Boise. Payette Brewing is a premier post-race location for your after race celebrations. We'll have awards on the main stage, a large fire pit and of course... all your post-race beverages.
