Some obstacles are venue specific and built around unique terrain features. We don't give you maps - the element of surprise is part of the adventure. There can be fire, mud, barbed wire, water, ice - things to crawl under, jump over, balance on, carry, drag or pull yourself up on. You won't know what to expect, or when to expect it . Get over it and get on with it!
