If you live in the London area and have plans tonight, cancel them. This evening sees hundreds of riders turn out for the third Rollapaluza Urban Hill Climb on Swains Lane, Highgate from 6.30-8.30pm.
It's an 800m, lung-busting sprint that tests speed and power to the hilt. Unfortunately entry closed yesterday but it's the sort of event that's as good to watch as it is taking part. It's free to watch, too, so will give you a look at what it takes for next year.
