This spring event at Marshall Mountain in Missoula, MT invites young runners to experience scenic wildflower-lined trails with three fun options: a free 1K run, a 2-mile trail run, or a 4-mile trail run (both $19), with all finishers enjoying ice cream afterward. All proceeds support Go Run Missoula, a nonprofit providing non-competitive running and strength-training programs for 3rd–8th grade female and non-binary youth. You can also check out the Second Annual Marshall Mountain Revival Runs the day before, which offers team relay, 5-mile, and 25K distances for runners looking for more options.
