kennard raises horses for rodeo... - go! - for riding, and for this-- indian relay racing. - the athletic ability on them kids are just amazing. the competition is intense. bourdain: they travel all over to compete at this collarbone-smashing, skull-cracking, bone-snappingly dangerous sport-- former allies and former blood enemies alike. - it requires a lot of courage. - i'll bet. - and a high threshold for pain. it's representative of warrior mentality. welcome! bourdain: one rider, three horses. - they're all in line. - when they're lined up, gun goes off. it's like a spontaneous combustion. - away they go! [whistling and cheering] bourdain: top speed is around 40 miles an hour. and after each lap, the rider dismounts at full freakin' gallop and leaps, hopefully, onto the next horse. yes, it's as dangerous and difficult as it looks.
