They flip, they fly, and they fling themselves around a horse as it gallops through the rodeo ring.

While it's both a thrill and a terror for the riders in the North American Trick Riding Competition during Rodeo Rapid City at the Black Hills Stock Show this week, fans are the real winners during the entertaining show.

Several competitors from across the continent gathered in Rapid City and performed their best horse riding tricks on Wednesday in the preliminary round of the event.

The riders will convene again at 1 p.m. today for another round, then compete for the title during the PRCA rodeo at the Rushmore Plaza Civic Center at 7:30 p.m. today.
