1. Jurassic Classic Mad Run
Located in Southern California, the Jurassic Classic thrives off their mud pits. A 5k seems like an easy task, but add in walls, cargo nets, muddy hills, and mud pits that slow you down, and your legs will be burning just one mile in. There are two individual waves, a team wave, so you and 3 other friends can support each other, and a kids wave, so they don’t miss out on the fun.
