Daris is out in front, and feels great. He hits mile thirteen, and Matt Hoover -- burly winner of season two -- is there. Matt joins him for a few miles, which is a welcome distraction. Koli is feeling the pain, but at his mile thirteen he sees Sione! And guacamole, has Sione put some weight back on. He can still jog, though, and gives some nice encouragement to Koli. At mile marker 11, Ali Vincent pops out and gives Ashley a giant hug. Ali is still fit as can be. Mike's special guest is season seven finalist Mike Morelli -- cute, young Mike! -- who has maybe gained a tiny bit of weight back but overall looks really good. Our Mike is psyched to see him.

Matt tells Daris that the hardest part of a marathon for a lot of people is mile 20. Daris is ready to crush it. Matt bids him adieu with instructions to kill it. Daris does. Mike, however, feels pretty crushed and is in serious pain between mile 15 and mile 20. He keeps walking, though, and vows to finish. Emo music plays as the contestants get closer and closer to the finish line, and have some supporters to cheer them on. Daris's goal is to complete the marathon in about four hours. He doesn't want to be the former fat guy who finished the marathon -- he wants to be a marathon runner. And that's where he's going. At mile 23, he sees dolphins! Also his sister, who runs with him for a while. Daris looks at her, decides to push it, and takes off. His poor sister is left behind, but this might work to her benefit since now she doesn't actually have to run anymore.

Daris, clearly ahead of the pack, reaches the finish line. And aw, crap, I'm totally crying. He makes it across with a time of four hours and two minutes. This kills Tara's previous time. Daris takes a minute to catch his breath, and looks like he would really enjoy this moment were he not so severely exhausted. Koli, meanwhile, is loving the ocean and the perfect weather. Sione reminds him that quitting is not an option, and he can get through the last few miles. At mile 24, Sione picks up the pace. Koli keeps up, figuring that the faster he runs the faster he gets this over with. That's always my strategy, too!
