The World Championships are in the United States this year. I'm watching the men's road race live on CNBC as I type this. It's on the streets of Richmond, Virginia. The winner gets to wear the rainbow jersey for the next year.
Addendum: Peter Sagan of Slovakia, a fan favorite even in the United States, is the new World Champion. Here is video of the final six kilometers. Sagan averaged 26.01 miles per hour for 162.4 miles. As a cyclist, I find that mind-boggling.
