Boom

Here's an interesting one - Who was the last rider to hold the yellow, green, polkadot and white jersey simultaneously?

In this instance, it was Rabobank's Lars Boom, after his impressive debut in the Paris-Nice Prologue.

"I gave everything I had knowing this was a course for me, with a little climb at the start and a fast hard, flat course afterwards. I expected a good time but maybe not that good. To beat riders like Contador, Sanchez and the rest is just fabulous. My best result to date was winning a Vuelta stage. Now I’m hoping to retain the yellow jersey in the next couple of days knowing that with the first climbs, it’ll be hard to stay with the best."
