Mark Cavendish is a busy man. The ace sprinter from the Isle of Man has raced in Belgium and France since missing out on an Olympic medal last weekend. He's now expected in the Netherlands.

No one would blame Cavendish, who rode the Tour de France in support of Bradley Wiggins earlier this month, for taking some rest after such a grueling schedule. But rest is a word he doesn't seem to know.

The fastest man on a bike will be back in the Olympic arena as soon as Thursday in the role of a BBC presenter.

Don't speak too fast, Cav!
