John Wayne's granddaughter and a descendant of legendary American frontiersman Daniel Boone are among the problem solvers who have signed up for the 22nd season of The Amazing Race.

Jennifer Kuhle and Caroline Cutbirth, who are also bandmates in country act Stealing Angels, will compete for the $1 million prize alongside familiar faces like former ice hockey star Bates Battaglia and his brother Anthony.

The new season of The Amazing Race begins on 17 February (13).
