Mike wants to finish with Ashley, who is a little ways ahead of him. He decides to run and try to catch up. He has no idea where he got the energy and power to do so, but soon enough he's there. Ashley is happy to see him. She's really hurting and struggling with her knee, but she takes off with Mike by her side. At mile 25, Koli's sister waits for him. She joins him in running, and Koli starts to get emotional. He finishes strong, and crosses the finish line with a time of six hours and eight minutes. He heaves and gasps for breath and cries, and then his sister cries, and then I cry, too. Thankfully, Dr. Huizenga is there to make sure that no one dies. Koli is amazed that he's gone from not being able to run a mile to a marathon in six months. He says he's proof that anybody can do this with some hard work.

Ashley and Mike hit the final stretch. At mile 25, Ashley's brother waits for her. Mike's sister Mariastella is there, too. Ashley breaks down completely, she's so happy to see her brother, and Mike gives Mariastella a huge hug. They all take off again and cross the finish line with a time of six hours and twenty-six minutes. They really weren't far behind Koli at all! There is much celebration and hugging, and then everyone gets a giant $10,000 check!

With the running and the celebrating over, it's time for the penultimate weigh-in. The two people with the highest percentage of weight loss will be above the yellow line, and guaranteed a spot in the finals. The two people with the lowest percentage of weight lost will fall below the yellow line, and have to plead with America to vote them in the top three.

Mike is first to weigh in. He weighed 322 pounds when he left the ranch, and now weighs 299 pounds. That's a loss of 23 pounds. He definitely seems relieved, and in fact starts crying. He says that for his entire adult life he couldn't get under 300 pounds. And now here he is. Sami even gets a little teary as she congratulates him. In his month at home, Michael lost 7.14% of his weight, which Sami notes is a high standard for everyone else.
