Dennis starts the race alongside Whit, who informs Dennis that he intends to move Libby and Jake to Chicago, Illinois. Angered, Dennis insults Whit and they tussle for a while at the start of the race and, in their efforts to outdo each other, they catch up to and then overtake the professional runners, and suddenly Whit trips Dennis and badly injures him. Stretchers prepare to take Dennis to the hospital. Whit continues, but is taken to the hospital after feeling ill and feeling pain in his leg. Libby goes to the hospital to find Dennis, but only finds Whit, who claims loudly that his injuries are the result of Dennis deliberately tripping him. The doctor tells him he is not actually injured and has only hit the wall. Jake is playing with Whits hospital bed, and to Libbys horror, Whit calls him a little shit.Dennis has in fact refused to be transported to the hospital or even get medical attention and is continuing the race well into the afternoon and evening with a sprained ankle, accompanied by a growing group of supporters, including Gordon and Mr. Ghosh Dastidar. An exhausted Dennis almost hits the wall but after an emotional inner struggle, his resolve to complete the race is restored. Later at Whits house, Libby, Jake and Whit, watch a television replay of the WhitDennis tussle, as the replay shows that in fact Whit had deliberately tripped Dennis and had fallen over because Dennis pulled him down as he was falling. As Whit tries to justify his behaviour, he blurts out his intentions to have Libby and Jake move to Chicago with him. A furious Libby puts the engagement ring on a table, telling Whit nobodys perfect and storms out with Jake. The two go to meet Dennis as he arrives at the finish line. Dennis falls over just metres from the finish line and cannot get up until he sees Libby and Jake calling to him at which point he gets up, sprints to the finish and collapses in their arms. ........
