Matt, Danny and Blake head to Central America to take on the untamed jungles of Belize. This four-day, 75-mile journey takes them from one of the country’s highest points, the shrouded Victoria Peak, to their finish line at the Caribbean Sea. Few humans ever have walked this terrain, and nobody has attempted to run it – with good reason. Along the way, the guys face brutal terrain, torrential downpours, oppressive heat and humidity. And, to make things worse, they encounter deadly snakes, spiders and crocodiles. The merciless conditions finally may prove too much for these best friends.
