The Amazing Race Returns

Playing in the NFL is one thing, but competing on The Amazing Race is a whole different beast.

“This might be the most unpredictable season yet,” Phil Keoghan, host of the hit CBS reality competition, tells PEOPLE.

“[Teams of] pro athletes, feisty fit couples, people with practical hard-working skills, book smarts and strong friendships make it almost impossible to predict who will have an advantage,” he says.

Amazing Race: Host Phil Keoghan Picks a Winner

Amazing Race host Phil Keoghan swears on his passport that season 17’s finale, which airs Sunday on CBS, is chock full “memorable and very cool moments.”

And that’s saying a lot considering this season saw a contestant get a runaway watermelon to the face, an on-air proposal, the longest penalty and a team who slept through their pit stop departure time by more than two hours.

Phil Keoghan to Take His Own Amazing Race

He’s no stranger to observing overwhelming challenges, but by his own estimation, “This is the most daunting physical thing I have ever attempted,” Amazing Race host Phil Keoghan tells PEOPLE about his own amazing race – a 40-day, 39-city cycling tour from Los Angeles to New York.

Starting this Saturday, Keoghan, 41, plans to average 100 miles a day in pedal power. “Riding a bicycle is about getting back to basics,” he says. “It’s good for the waistline and it’s good for the wallet, is what I’m saying.”

Nicole's Man Burns the Midnight Oil

So now that he got down on one knee and popped the proverbial question, and Nicole Richie is likely off planning their wedding, what is her intended, DJ AM (real name: Adam Goldstein), doing with his time? Planning a reality show, natch. Says DJ AM: “Let’s just say it’s like Dr. Phil meets DMC DJ battle videotape,” referring to the most prestigious of the DJ contests. Of course, he’ll have to work on the show in between club gigs – every month, he plays four dates in Las Vegas, two in San Francisco and Los Angeles, and one each in London, Manchester, and Toronto.
