@toughestrace: The hardest obstacles are not built of metal or wood. They live in your head and challenge you every single day. Hats off to all you 220k runners who've crossed the finishline since 2013! You earned our respect from the moment you showed up at the starting line. Are you ready for your next adventure!? Thanks to @tedywarsitha for the POV footage 👏 #toughest #beatyourobstacle #ocr #obstacle #extremesports #obstaclecourse #obstaclecourseracing #race
