Runner's Almanac - Biggest Loser Marathon

I haven't been watching NBC's Biggest Loser faithfully like last season, but I did watch last night's marathon episode (most of it). It's unclear what kind of training they receive, since they are told of the marathon about one month or so prior to the event. Although considering that it has become a regular event on the show, they should have expected it. What they don't show is all of the off-scene support I am sure they must receive - First Aid, food, or anything else. Rudy supposedly came in first with a time of about 5:15 - which is my marathon goal. The course they run looks great - with hills, sand, oceanside views, trails. They should make this a real marathon!
