Goliathon is a unique 4-mile, Ninja Warrior style, non-profit obstacle course event created to help those in need around the world. Its management team and staff are 100% volunteer and all proceeds go directly to clean water projects in developing countries. Goliathon was the first obstacle course event to tier its obstacles. Each of its 12 obstacles have three tiers to choose from: G1 moderately easy, G2 difficult and G3 extreme. Families, friends and teams with different abilities can run together and choose the level of difficulty on each obstacle that's right for them.
