Virgin, UT. Introducing a new racing format we are testing out- small group half marathons. This course is challenging, but is not exclusive to experienced runners. Keep in mind, this is a trail race, and you’ll be running in the dark, so don your headlamp and get ready to run under the full moon in Zion. Runners will sign up to run their half marathon during a specific time slot. Each time slot allows up to 50 runners in each race.
