Moab, UT. 9K, half marathon, 50K and 50 mile. Arches Ultra is Moab’s newest trail race, and it travels along the border of Arches National Park, using Bar M, Klonzo, and Klondike Trail Systems. The trails are smooth and easy at points, technical slick rock at others, and there’s even some sand to shake things up. Winter is a great time to be in Moab running, and we’ve chosen a lower elevation run, that will give you views of the towering Moab cliffs, Arches National Park, and the snow covered La Sals.
