When the going gets tough, the tough get going! The Central London path isn't for newbies. Taking its start at Westminster Bridge, the 20-mile-long stretch was included as a part of the 2012 Olympic Cycling Route – just try it out and see why. Then, when you've made it all the way to Box Hill and still feeling cocky – how about to try and ride your way up? On a windy day, you may find it quite a tricky task to accomplish so it's best if you have weather on your side. The climb stretches a little over 1.5 miles, so you will be feeling where your muscles are, there's no doubt about that.
