Tough Mudder

Watch as competitors tackle the 15K with 20+ obstacles or the 5K with 12+, and navigate technical woods and horse trails designed to test their dignity. Survivors get to nab a fresh T-shirt, a shiny medal and that iconic headband to prove they actually did it. Grab a spectator pass, $25, to watch your friends while you enjoy the festival vibes. Plantation Field, 322 Apple Grove Rd., Coatesville. 7:45 a.m. ToughMudder.com/Events/Philly
