CBS has announced The Amazing Race's upcoming 29th season will premiere with a one-hour broadcast on Thursday, March 30 at 10PM ET/PT, ditching the network's original plans to debut the show on Friday, April 21 at 8PM ET/PT. (CBS had announced the initial April 21 premiere in late November 2016).
Due to poor ratings, CBS' new Training Day series is being moved from Thursday to Saturday nights, so The Amazing Race will take its place on Thursdays.
Training Day will now air its seven remaining episodes on Saturday nights from 9-10PM ET/PT beginning on April 8.
Undercover Boss will replace The Amazing Race in its previously-planned time period after the season finale of MacGyver and return with four new episodes beginning Friday, April 28 from 8-9PM ET/PT.
While Season 12 of The Amazing Race had initially been scheduled as a mid-season series for the 2007-2008 TV season, it ended up debuting in early November 2007 after one of CBS' new fall series, a musical comedy called Viva Laughlin, flopped and was canceled after only two episodes.
Last season of The Amazing Race featured teams known for their social-media influence. The show wrapped in May 2016 with "Engaged Couple" Dana Borriello and Matt Steffanina winning the $1 million.
