The Amazing Race 26 cast definitely has the right stuff: New Kids on the Block's Jonathan Knight will be racing around the world.

Knight will race with his partner Harley Rodriguez on the first-ever all-dating couples season, which will feature five teams meeting for "blind dates" at the start line.

"Usually we have people who know each other really well. In this particular case we have five blind dates and six regular dates," co-creator Bertram van Munster said in a statement. "Going on a blind date to a restaurant is one thing, but going on a blind date around the world is like rolling the dice in a big way."

Must-see new winter shows

The cast also includes Olympians Aly Dudek, who won a bronze in short track speed skating in Vancouver, and Steven Langton, who won two bronzes in bobsledding in Sochi. Among the blind date couples are two lawyers, a nurse and Navy physician, and a human resources rep and pageant consultant.

Season 26 will cover 35,000 miles over five continents and eight countries, including visits to Bangkok, Namibia and Monaco. The season's new twist will be the Date Night reward, given to one lucky couple to enjoy some alone time together.
