Rocky Mountain Rollergirls teammates on next season of The Amazing Race?

Although the official cast list for the 22nd season of the CBS reality series The Amazing Race hasn't been released, Reality Fan Forum, Reality Blurred and other sources are spilling the beans early, and report that a pair of Rocky Mountain Rollergirls will be among next season's competitors. Google away if you're after more spoilers; for now we'll keep it to this: Beth "Fiona Grapple" Bandimere and Mona "Triple Shot Misto" Hinman-Egender, the names being reported, are teammates on RMRG's 5280 Fight Club, winner of the 2010 Women's Flat Track Derby Association national championships.

Contestants on the show are contractually bound to keep quiet until official announcements are made; RMRG spokeswoman Meghan "Undertaker's Daughter" Dougherty could not confirm the Amazing Race news but did confirm that both skaters are currently with the league.

Fiona Grapple is co-captain of the 5280 Fight Club and also skates for the league's local Sugar Kill Gang squad; Triple Shot Misto is a jammer for 5280 Fight Club and also skates for the league's local United States Pummeling Service squad.

"They both play on the travel team, they're both hard hitters and fast skaters -- Misto is an ex-speed skater -- and they both jam and block," says Dougherty. "They make a pretty formidable pair in anything they do."

The next season of the race premieres on February 17, but you won't have to wait quite that long to see them in action: the Rocky Mountain Rollergirls' 2013 season opens on February 2 at the Fillmore Auditorium.
