Ken and Gerard, on their bikes, reach the beginning of the course. They grab a cab. The driver seems to know where they need to go, so they put their faith in him and take off. From the taxi, they see FloZach walking up from the boats. "They must be there and back already," Gerard says. Meanwhile, Zach is assuring Flo that no one else had an easy time with the Detour either.
Speaking of which, here's Teri, walking the bike along the course. In fact, by the time she reaches the later part, she's not even touching the bike -- she's got kids pushing it for her. Oh, come on, now. I realize that Ian and Gerard did one thing by having people keep them from tipping over while they pedaled or scooted the bike, but Teri cannot possibly have believed that it was within the rules of the Detour to have the locals push the bike for her while she walked along. At the end of the course, her helpers mob Ian, wanting money, which he hands out. They pull the clue and head back on the regular bikes.
