And then, good people, it's marathon time. The final four stand at the starting point, which is the desert scene where they had their very first one-mile running challenge. Sami tells them that the only way to guarantee a spot in the finals is to beat one another on the scale, and beat the 11 eliminated players in the marathon. A bus pulls up and the door starts to open, and then we cut to commercials like we haven't seen all these bitches in the "Where Are They Now?" segments already. I'm not going to review all of the contestants, since we'll be seeing enough of them and their skinny selves next week. The contestants line up by the numbers on their shirts, which again represent their ages. Sami reminds everyone that they're competing for a spot in the finals. But they're also competing for something else! The 5th place finisher will get $2,500; 4th place will get $5,000; 3rd place gets $7,500; 2nd gets $10,000; and the winner gets $25,000. Not bad, especially considering how many of these people are currently jobless. Bonnie is having knee surgery the week after this, so opts to sit out. That's the best for everyone, isn't it?

The contestants take off, and we get a tour of the marathon path. It goes through desert, pavement, dirt road and then back to the desert for the last 14 miles. By "desert" I mean "dry lake bed." Per usual, watching people run is just fascinating, so the marathon is peppered with inspirational clips from contestants past. Courtney is just barely in the lead at mile one. Sunny tells us that she, Joe, Becky and Antone are doing intervals the whole way -- a five minute run and five minute walk. As a short-term goal enthusiast, I really love intervals. I finished Couch to 5K and then started doing intervals again, and it made me FASTER. No lie, people. It has the added advantage of not making me want to die. I have asthma and a bum knee! Running makes me wheezy and creaky! Joe has a bum knee, too, but tells us that he is finishing this damn race. Then Sami takes a minute to tell us how lazy and fat we all are. I KNOW. God. If you visit nbc.com/walgreens, you can walk your way to some rewards, if that's the kind of thing you're into.

Jessica tells us that she wants Courtney in her view, and that she hopes Courtney's going to peak early and tire herself out. Boston Johnny wears a Music Man hat and is weird a whole bunch. Patrick is in the middle of the pack, and says he's using a tortoise and hare strategy. Ramon is feeling good, and he and Jessica stay side by side like the two lovebirds they are. At mile six, Courtney is still in the lead, and Dolvett joins her for a little run and words of encouragement. Bob joins Vinny, who is more shuffling than running, I'd say. Anna joins Joe, who has only the kindest of words for her. She loves him too. Jennifer sees Bob and starts crying, as she is wont to do. I still see her as having Kathy Bates in Misery tendencies. And Bob really likes his knees.
