Tough Mudder, a 10-12 mile obstacle course competition founded by a former British counter-terrorism agent to test mental and physical strength, will be held at the Missouri State Fairgrounds in Sedalia, Missouri on October 8-9, 2016. Over the past 6 years, more than 2 million participants in over 150 Tough Mudder events have raised over $10 million for charity. The Sedalia event will feature over 20 obstacles for teams to navigate across the fairgrounds' open spaces and arenas.
