Red Bull Crashed Ice, which began in March 2001, is a world tour event in which racers (typically former ice hockey players) descend a steep ice canal filled with bumps, jumps, and rollers and obstacles four at a time, jostling for position as they reach speeds of up to 45 mph. This year's season opener was held on Nov. 27 and 28, in Quebec City, Canada.
Red Bull GRC is a revolutionary new form of motorsport. Some call it a cross between rally and supercross. It features wheel to wheel racing with up to 10 cars competing at once in fast paced heat races over huge jumps on combination dirt and asphalt courses around the world. Watch world champions, crossover legends and others battle it out to be the global champion. Contributing Sports Illustrated photographer Erick W. Rasco covers the New England Global Rallycross racing this past weekend at Thompson Speedway Motorsports Park in Connecticut.
The Birdsville Races, first held in 1882, are a two-day horse racing event held annually in September in the Channel Country of Central West Queensland, in Birdsville, Australia. The small town was originally known as Diamantina Crossing and was established in the 1800s as a center for stock routes for cattle country and as a customs collection point. Today it has a population of about 100 people. Photographer Sharon Chapman went Down Under to get up close and personal for this year's competition.
