Dutchman Lars Boom completed a triple crown in cyclo-cross racing by winning the men’s World Championship race in Treviso on Sunday.

The 22 year-old took the 2003 Junior and 2007 Under-23 world titles. Only Czech cyclist Radomir Simunek had previously won all three.
The Dutch rider won by just six seconds over Czech Zdenek Stybar and Belgium’s Sven Nys. ‘I am very pleased,’ Boom said after his win.
Cyclo-cross is a mass bike race consisting of many laps of a short course including wooded trails, grass, steep hills and obstacles, sometimes requiring cyclists to dismount and carry their bikes.
