Run13, Provo

For runners at the starting line of Run13, LLC's signature half-marathons, 10Ks, and 5Ks, it's all downhill from there. The organization plots many of its events on a breezy downhill route, giving beginning runners a leg up on their first race and experienced runners a better shot at a personal record. But runners aren't the only ones that benefit. The Racing Cane 10K, 5K, and 1K benefits children in the Dominican Republic's impoverished cane-shack communities, using shoe collections and race registrations to help them break out of the cycle of poverty. And for every race, the organization designates a charity to donate its proceeds to, often taking suggestions from its fans or the magic 8 ball that presides over all affairs.
