You can choose from six routes, all heading to central London. They set off at 08:00 every Friday from 14 August to 2 October.
There even will be a few marshals from LCC to help you on your way and they will also give your bicycle a quick check over.
Yes I’m a bit late on this, but I just learned about it, but that is not an excuse for you not to get back on your bike :)
