The Amazing Race 31

The Amazing Race 31 (also promoted as The Amazing Race: Reality Showdown ) is the thirty-first season of the American reality competition show The Amazing Race. Hosted by Phil Keoghan, it featured eleven teams of two, each consisting of former contestants from CBS's flagship reality shows, Big Brother, Survivor, and The Amazing Race, competing in a race around the world in order to win US$1,000,000. This season visited four continents and ten countries and traveled over 25000 mi. Starting in Hermosa Beach, California, racers traveled through Japan, Laos, Vietnam, the United Arab Emirates, Uganda, Switzerland, Croatia, the Netherlands, and England before finishing in Detroit. A new twist introduced in this season was the U-Turn Vote. The season premiered on CBS on April 17, 2019, and the season finale aired on June 26, 2019.

All three of the final teams consisted of returning players from previous seasons of The Amazing Race. Life partners Colin Guinn and Christie Woods, who had competed on The Amazing Race 5, were the winners of this season. Best friends Tyler Oakley and Korey Kuhl, who had competed on The Amazing Race 28, finished in second place; and cousins Leo Temory and Jamal Zadran, who had competed on The Amazing Race 23 and The Amazing Race 24, finished in third place.

Development and filming
On June 10, 2018, Phil Keoghan announced on the show's social media accounts that the season had begun filming and that the teams would be composed of contestants from CBS's reality competition programs. On June 30, teams were spotted at the Nieuwe Toren in Kampen, Netherlands. On July 3, filming concluded in Detroit, which featured a performance of The White Stripes' single "Seven Nation Army" that was originally planned to be set in Belle Isle Park. However, the permit was denied as the Michigan Department of Natural Resources had not been informed about the large gathering of musicians needed for filming.

The Amazing Race 31 traveled over 25,000 miles across four continents and ten countries, including first-time visits for the American edition to Uganda and Laos. Laos was previously visited on the fourth season of The Amazing Race Vietnam.

The Head-to-Head returned this season after it was introduced in the previous season. This season is also the first to utilize the U-Turn Vote, which has been previously utilized by the Israeli, Chinese, Australian, and Filipino versions of The Amazing Race.

 * Detroit (Fort Wayne)
 * Episode summary
 * At the start of this leg, teams were instructed to fly to Detroit, Michigan. Once there, teams found their next clue at The Spirit of Detroit.
 * In this season's final Roadblock, one team member had to rappel face-first 500 ft down the Guardian Building. On the way down, they had to look for a series of numbers that they needed to unlock a bank vault in the basement of the building in order to retrieve their next clue.
 * After the Roadblock, teams had to travel to the Fowling Warehouse and play a game of fowling, which required each team member to throw a football and knock down bowling pins in order to receive their next clue.
 * At Third Man Records, teams had to properly press five two-tone vinyl records using Amazing Race colors in order to receive their next clue, which directed them to Hart Plaza. There, teams had to search amongst a group of Rockin' 1000 musicians to find their next clue atop a drum. Teams then had to assemble a five-piece drum kit that precisely matched an example while the musicians played The White Stripes' single "Seven Nation Army". Once the drum kit was correctly assembled, the lead drummer gave teams their final clue, which directed them to the finish line at Fort Wayne.
 * Additional notes
 * After leaving the Fowling Warehouse, teams had to travel to the Heidelberg Project and search through a field of Amazing Race clue boxes scattered throughout the outdoor art installation for one which contained their next clue. This task was unaired.
 * Legs 11 and 12 aired back-to-back as a special two-hour episode.

Critical response
The Amazing Race 31 received mostly positive reviews. Andy Dehnart of reality blurred called this season dull, writing that "TAR can still deliver beautiful cinematography and entertaining moments, like Rupert talking to an elephant, but the structure of the legs constantly undercuts any actual racing by evening up the teams." Jodi Walker of Entertainment Weekly wrote that "more reality TV competition cultures in the mix made for a little more drama than usual." The "Purple Rock Podcast" praised the cast, strong racing, and overall story saying that "this experiment paid off accordingly." In 2022, Rhenn Taguiam of Game Rant ranked this season as the second-best season.

Critics were also positive towards the growth of Colin & Christie compared to their previous appearance. Tamara Grant of CheatSheat called it "a true redemption arc because of their behavior on Season 5." Dalton Ross of Entertainment Weekly called it the "most radical reality show transformation ever."
