And then they're off! Danny is wearing his support hose. And you know what happens in marathons. People run. And in this case, they narrate, too. These bitches are backing up all sorts of traffic. Rudy's goal is to run the whole time and finish under five and a half hours. Danny and Liz run together, but agree that either of them can go ahead if they want to. They reminisce about their time together on campus, and recognize the special bond between them. They really are totally supportive of each other, which is lovely to see in this cutthroat world of yellow lines. Liz and Danny walk for a bit at mile three, and then season seven's Tara jumps out from behind a hill and starts to run with them. She gives them a second wind, and Liz talks about the joy of seeing Tara win the challenge where she had to pull a car. Tara tells the two of them that at a certain point in the marathon adrenaline is going to take over and make them finish when they think they can't.

At mile thirteen, Rudy meets up with his former partner Dina. She's looking pretty great. He's happy to see her, and she runs alongside him with a big smile. Amanda gets support from her BFF Brian at mile thirteen. He runs alongside her, and Amanda redoubles her effort to finish the marathon. Things aren't going so great for Danny, though. His legs hurt. His hips hurt. His knees hurt. He has odd sweat marks on his shirt. You know, I think he might be wearing a manssiere! Liz wonders if she might have to figure out how to do this on her own. At some point, Amanda's body starts to break down some and she begins crying. And then Tara joins her! Tara is like the magical running fairy. She makes you stop being a wimp. And, I mean, Amanda is trying to be a wimp something fierce.

Danny's wife and Liz's husband meet them at mile thirteen. Meanwhile, Amanda cries. I guess I'd be crying too. After all, I'm already crying because of my couch-related broken butt injury. Rudy is running out of gas, too. Dina cheers him on. Danny looks like he's going to burst every blood vessel in his body. He doesn't know if he can do it. Amanda gets a lot of support from Tara and Brian. They push her to fight through the pain and run. And then Rudy's in the home stretch! The last mile of the marathon is the mile that the contestants had to run on the very first episode of the show. You know, the one where Tracey almost died. Bob runs with Rudy for the last mile, and yells to onlookers that Rudy is a marathon runner. Rudy crosses the finish line at just under five hours and thirteen minutes. Helen and Mike from last season are waiting to greet him at the finish line, and we see Fat Rudy's message to his skinny self. And, ooh. I think Helen's had a little face work done. Eh, good for her. You have to nip and tuck that extra skin, I think.
