Down & Dirty Mud Run, Bronx

Covering oneself in mud, clambering up a jungle gym, and crawling through a tunnel is not how most people spend their Sunday mornings. But for competitors in the Down & Dirty Obstacle Race Presented by Keyes Automotive Group, it’s business as usual. During a three- or six-mile run, participants test their endurance and strength as they tackle more than 20 challenges in between sprints. These include leaping over marine hurdles, walking across balance beams, and clenching your teeth until tiny wings sprout from your ankles. Youngsters can join in on the fun, too—the Adventure Kids course pits ages 4–13 against child-sized obstacles and a mud pit. Following the race, winners in their division earn awards, then celebrate during a post-race after-party.
