The Amazing Race Wraps Season 31: Who Will Win?

This season of The Amazing Race was billed as an all-star clash between stars of CBS's three big reality shows: Race, Survivor, and Big Brother. But as it turns out, people who have run The Amazing Race before are a lot better at running The Amazing Race than other people, so this season has been a systematic whittling down of the outmatched Survivor and Big Brother players. One relatively unsung development this season: Race faves Tyler Oakley and Korey Kuhl won four consecutive legs this season and, combined with their five legs won in a previous season, now hold the record for most legs won all-time. Not bad for a pair of cute social-media gays.

SEASON FINALE: Tonight's two-hour Amazing Race season finale will see the final four teams race through London and Detroit, where they'll rappel nearly 500 feet down the Guardian Building. While CBS previews appear to have inadvertantly revealed the fourth place finisher, you'll need to tune in to see who wins the $1 million.  8:00 PM ET on CBS

DEBATE NIGHT, PT 1: NBC's First Democratic Presidential Primary Debate will split the top 20 Democratic candidates into two groups of 10 over two nights. The first group is headlined by Massachusetts Senator Elizabeth Warren, New Jersey Senator Cory Booker, former Texas Congressman Beto O'Rourke, and Minnesota Senator Amy Klobuchar. They'll be joined by former HUD Secretary Julian Castro, Washington governor Jay Inslee, Ohio Representative Tim Ryan, former Maryland Representative John Delaney, Hawaii Representative Tulsi Gabbard, and New York City mayor Bill De Blasio. Among tonight's group, Warren has been the best performer in early polling by a wide margin, and she's looking to keep her momentum going here. The debate will be moderated by Lester Holt, Savannah Guthrie, Rachel Maddow, Chuck Todd, and José Diaz-Balart. 9:00 PM ET on NBC, MSNBC and Telemundo.
