Ratings: Big Bang Beats Idol Head to Head Again, But Fox Wins Another Low Night

Phil Keoghan is gearing up for a big weekend. On Saturday, his documentary The Ride - in which he biked across the U.S. to raise money for the National Multiple Sclerosis Society - premieres on Showtime at 8/7c. On Sunday, The Amazing Race returns for its 20th season (8/7c, CBS). "[The scheduling] was not planned. It just ended up being that way," Keoghan tells TVGuide.com. "The great thing is it's almost three years to the day I started my bike ride and we just hit the $1 million mark. Now the teams are starting their Race for $1 million. One's for charity and one's a race around the world, so it's pretty cool." What was planned though was having Racers start off their globe-trotting adventure on - what else? - bikes, and infusing the season with a wee bit more drama by casting everyone's favorite Big Brother couple they love to hate: Brendon and Rachel. We caught up with Keoghan to get the scoop on Season 20 and why it's not to be missed.
