Ok, it's on More4 tomorrow at 2.30 and 3.30, then obviously More4 +1 at 3.30 and 4.30.
Basically a group of fat Americans are walking from the start line of the Boston Marathon, over 550 miles to Washington DC. Prize money of 1.2 m for whoever loses the most weight, and gets to stay in instead of being voted out
They are taught nutrition as they go along, and do challenges, etc. Very Biggest Loser
Seen some of it before - interesting concept but seems a bit risky to me. Some of them are very heavy and you would think the sudden and dramatic nature of the walk would be a real strain on their hearts and joints. Still, very interesting prog all the same!
