Along with the intense speed and close proximity of competitors, it’s the crashes that make track racing so exciting, much like NASCAR but more so. The UCI World Track Championships, which wrapped up in Poland on Sunday, provided some spectacular collisions and spills. Gregory Bauge of France was nearly taken out in the semifinals by a collision fellow Frenchmen Kevin Sireau, but kept the rubber side down and went on to beat Azizulhasni Awang of Malaysia for the world sprint crown. Guo Suang of China claimed her first world title in women’s keirin. Leigh Howard of Australia won the men’s omnium, a combination of five events. Finally, Giorgia Bronzini of Italy won the women’s points race, an event marked by a number of pileups, the sort the Red Hook Criterium lacked.
