Out YouTube stars Tyler Oakley and Korey Kuhl are among the three final teams as season 28 of CBS' The Amazing Race wraps on Friday.

The best friends, who together co-host the popular podcast Psychobabble, are attempting to become the first gay team to win the $1 million prize since married couple Josh Kilmer-Purcell and Brent Ridge won the show's 21st season in 2012.

“We're ready,” Kuhl said at the pitstop in last week's episode.

“We're not jet lagged at all, surprisingly,” Oakley said. “I am just so thankful for the opportunity. No matter what happens to be able to run the entire race. We have been talking about it and this has been like a thing that we have thought about for so long. And now to finally get a chance to do it. We're just honored to go on the adventure.”

“I'm so happy I'm doing it with you,” Oakley added, pointing to Kuhl.

In Friday's final leg of the race, teams race from Shenzen, China to Santa Barbara and are challenged to jump off a building more than 150 feet high and perform synchronized mountaineering.
