Amazing Race lured 9.98 million (2.6 demo rating, a season low). Meanwhile, AMC's new drama, Hell on Wheels, became the cable network's second biggest series launch (behind The Walking Dead) with 4.4 million viewers at 10, where it premiered behind a new episode of Dead. The western also lassoed 2.4 million in the adults ages 18-49 demographic.
