Season 1, Leg 2
The series' first aired Roadblock, the only clue given to the teams was, "This task requires strong legs and keen eyes." One team member had to take the stairway up to the second level of the Eiffel Tower and use a coin to operate a telescope while the other team member had to search the skyline using the telescope to spot for the leg's Pit Stop, Arc de Triomphe, with a marked Race flag.
