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.
