Beauty queens, home-shopping TV hosts and a daughter and birth mother recently reunited after 20 years are among the motley cast of characters who’ll scurry tirelessly around the planet during the upcoming 17th season of The Amazing Race on CBS.

Among the more notable contestants: Miss Kentucky 2009 Mallory Ervin, competing with her father Gary; Jewelry Television host and Miss Oregon 2004 Brook Roberts, teamed with fellow TV host Claire Champlin; Internet comedian Kevin Wu (a.k.a., KevJumba on YouTube) and his father Michael; Princeton a cappella singers Connor Diemand-Yauman and Jonathan Schwartz; and birth mother and daughter Andie DeKroon and Katie Seamon.

They’ll be a tired bunch by the end of the race. This season, premiering Sept. 26, will cover 32,000 miles through 30 cities on four continents. The show will make first-time visits to Bangladesh, Ghana, and the Arctic Circle. And for the first time, the team finishing first in the premiere episode will get a surprise, game-changing advantage, according to CBS. – Tim Nudd
