Think you might have the heart, strength, endurance, puzzle skills, and winning personality to compete on MTV's The Challenge against the likes of Johnny "Bananas" Devenanzio, Wes Bergmann, Laurel Stucky, and Cara Maria Sorbello?

Well, you no longer have to appear on The Real World, Are You the One?, Big Brother, or Love Island in order to make your case. Fans now have the chance to audition for the show live onsite at several obstacle-filled Spartan races across the country.

Spartan races in Boston, Sacramento, and Los Angeles will feature pop-up Challenges with fan-favorite cast members. Devin Walker and Nicole Zanatta will be on hand for the Boston race at Fenway Park this weekend, Nov. 9 and 10.

The Sacramento race, hosted by C.T. Tamburello and Darrell Taylor, will take place at Van Vleck Ranch Nov. 16-17, and the Los Angeles event will be Dec. 7-8 at Castaic Lake State Recreation Area (hosts to be announced at a later date).

A fourth pop-up, hosted by Tony Raines and Jemmye Carrol, already happened in Atlanta. And Tony followed his hosting duties by running the race himself.

"Had to let everyone know what time it was at the @spartanrace in Atlanta today!" he wrote on Instagram. "Seriously what a great time I had participating in my 1st run. A big thank you to everyone on the MTV team and @spartan for having me, can’t wait for my next one! #spartanXthechallenge #TonyTime #Aroo."
