The Amazing Race - Season 7 Episode 10

The teams continue from their Pit Stop at a royal tomb in Jodhpur, India to Istanbul, Turkey --- more than 4,000 miles away. As the teams jockey for flights, two teams are caught by surprise when they learn that after believing they had a lead, they are in fact more than two hours behind. Once in Turkey, the teams participate in a sponsorship-placed gnome-finding task and then encounter a Detour which requires them to choose between Columns or Kilos. Most teams opt for Kilos, which requires them to weight people on a scale, but Ron and Kelly choose Columns, in which they have to use a coordinate grid to find columns with numbers and then use them as a combination for a lock. Later, a Roadblock requires one member of each team to rappel up a tall fortress and locate a key. The teams jockey for position heading for the Pit Stop, all while wondering about the significance of the gnome picked up earlier in the leg.
