"The World's Toughest Race" - probably is!  After a 17 year absence, Bear Grylls brings back Eco-Challenge on steroids, with a massive budget and plenty of stories, all on a bigger and badder course.  The 417 miles on Fiji, included all kinds of paddling, trekking, biking, ropes, and wading through hypothermia-inducing cold water; the 66 teams were given 11 days to finish, and for 22 teams, that wasn't enough.
