It's National Pizza Day! But how far do you have to ride to burn it off?

It’s National Pizza Day, apparently. And it’s quickly found a spot in my top five days of the year. But with a tummy now rumbling for pizza, the sensible voice in my mind is asking how many miles would I have to ride to burn it off?

Well, I don’t want to scare anyone, but the figures don’t make for fantastic reading. A basic Margarita from Pizza Express contains 729kcal while the delicious sounding Calabrese contains 1,346kcal.

But what does that mean in terms of riding? A little look at my last cyclocross race saw me burn off 364kcal for 1 hour of intense riding. At 22, with a high metabolism, it's a surprisingly low number. I had the pizza anyway...

A much longer Sunday ride of 4 hours burned 2,301kcal. It looks like I can have a starter and dessert as well, or a second pizza. Result.

The pros also love a slice of pizza occasionally, and if Nairo Quintana wants to beat Chris Froome this year, we might just have found the three-time Tour winner's weakness.

Now we think that if you've used 6,300kcal, you probably deserve a rather large pizza.

Being a climber is helped massively by being lighter

Now, I must point out, a few roadies in the office were quick to argue that cake is the undeniable staple of the British cyclist's riding diet. But which do you prefer as a reward for all those miles?
