Awesome show 
you can get it from a torrent site such as www.mininova.org
just search for Wipeout (there’s 2 episodes already).
I think it’s a re-make of a Japanese show (Takeshi’s Castle)
^or you can watch full episodes on abc.com
really is pretty good though… remake of MXC (most extreme challenge)
although the commentators arent as funny as MXC but still fun to watch
I watched one episode. Wasn’t impressed. :o
