The Amazing Race 24

The Amazing Race 24 (also known as The Amazing Race: All-Stars) is the twenty-fourth season of the American reality competition show The Amazing Race. Hosted by Phil Keoghan, it featured eleven teams of two, ten teams returning from previous editions and a composite team with two members that competed on separate seasons, competing in a race around the world to win US$1,000,000. This season visited three continents and nine countries and traveled over 23,000 miles (37,000 km) during twelve legs. Starting in Santa Clarita, California, racers traveled through China, Malaysia, Sri Lanka, Italy, Switzerland, Spain, England, and Wales before returning to the United States and finishing in Las Vegas. Elements of the show that returned for this season include the starting line task. The season premiered on CBS on February 23, 2014, and the season finale aired on May 18, 2014.

Father and son Dave and Connor O'Leary from The Amazing Race 22 were the winners of this season, while country singers Caroline Cutbirth and Jennifer Wayne from The Amazing Race 22 finished in second place, and Big Brother newlyweds Brendon Villegas and Rachel Reilly from The Amazing Race 20 finished in third place.

Filming for the season began on November 16, 2013, at Cougar Stadium at the College of the Canyons in Santa Clarita, California, with the returning teams spotted at Los Angeles International Airport later in the day. Filming was initially set to begin at the Rose Bowl, but was changed to Cougar Stadium due to "issues of availability to use the Rose Bowl." This season's course traveled 23,000 miles (37,000 km), across three continents and nine countries, including a first-time visit to Wales.

Illusionist David Copperfield appeared in the first Roadblock during the finale in Las Vegas.

In casting the teams for this season, host Phil Keoghan said that they sought to bring back teams that fans love as well as teams that spark the biggest fan reactions. One month prior to the start of filming, while the casting process was still ongoing, seven out of the eleven teams that appeared on this season were leaked through Twitter. Returning teams were ultimately selected from previous teams going as far back as season 14, including three teams competing for a third time.

Mark Jackson was originally set to compete with his original partner, Bopper Minton, but Bopper began showing signs of pancreatitis before arriving in Los Angeles for filming and was deemed unfit to compete by the production's medical team. As a last-minute replacement, Mallory Ervin flew in from Nashville to compete as Mark's teammate. This marked the first time that a team without a pre-existing relationship competed on The Amazing Race.

Leo & Jamal and Rachel Reilly returned to compete on The Amazing Race: Reality Showdown. Caroline & Jennifer appeared as clue givers during the finale of season 34 in Nashville.

Not long after this season aired, Natalie & Nadiya Anderson competed on Survivor: San Juan del Sur. Natalie returned to compete on Survivor: Winners at War. Nadiya also made an appearance as part of the loved ones visit. Natalie competed on the thirty-sixth season of the MTV reality show The Challenge, but withdrew in the fifth episode after learning that she was pregnant.
