Welcome | Outlaw Trail Ultra Half Marathon

Many of you have likely heard of an ultra marathon, what is an ultra half marathon? Well, an ultra marathon is anything longer than 26.2 miles, a ultra half marathon is anything longer than a 13.1 miles (it makes sense in our mind). Don’t worry though, the Outlaw in only about 1.4 miles longer than a true half marathon; no need to sweat. We love running trails and want to share one of our favorites with you. There is nothing better than “mostly” gradual downhill ultra half marathon to introduce people to the trials. Whether you are new to running, new to trials, or an experienced ultra-trail runner, this course is fun and beautiful.

Our Goal

Challenge and help everyone who desires it to run at least one trail ultra marathon in their lives, the Outlaw is a race that introduces runners to the trail with a shorter distance and easier elevation profile.

Race Proceeds

$10 per registered runner will be donated to the Magic Valley Trail Enhancement Committee to connect the Snake River canyon rim trail in Twin Falls, ID from the Evil Kninevel jump site to the Eastland/Poline corner.  This will connect the entire rim trail!!!  In April, 2016 approval for the trail was given.  Now the committee needs to raise money to cover the costs. Running the Outlaw will be awesome and at the same time you are raising money to help connect the trail. Also runners are encouraged to donate a needed item at the start of the race to go to the Valley House Homeless Shelter.

I had such an amazing experience! Everything was perfect, thanks for putting on such a great race! Not sure how you managed to pull the weather off, but it was perfect!
