Before you make the plunge and register, we encourage you to read through the “race info” and “course info” tabs and be sure you know what you’re getting into!  This is a very difficult mountain run, held in the spring.  Read through the website to find out what this truly means and make sure it’s your cup of tea before you register.


Can I change events at a later date?

Yes.  If you’re like many folks your spring training (or lack there of) might find you not ready to tackle the full 100 km or 60km that you signed up for and you decide that you’d rather opt for a shorter option. We will work to accommodate you, we will not however refund you the difference if you drop down to a shorter distance.

If you registered for a shorter category and you’d like to step it up to a longer category, we’ll also accommodate you and we will ask that you send us a check for the difference.

We will lock things down a 2 weeks  prior to the event, no changes will be allowed after May 22, 2016.

What does your race entry get you?

First off, the opportunity to run one of the most diverse, challenging, and beautiful trail running races in the country. Fully stocked aid stations, several of which are in remote locations.  As race directors, we take pride in involving the local Pocatello community.  In 2011 we were very fortunate to have the participation of several local artists for unique metals for finishers and beautiful pieces are art for the top 3 finishers in each category.  We’ll be doing something similar for 2016  You will also receive unique SMUT apparel, a great meal afterwards, free camping at the start/finish line, and a decent likelihood of winning some schwag from our great sponsors.
