London - Confused about entry-level TTs
Hey guys, I've been a roadie for about two years now but what I've always wanted to do is ride competitive TTs. Recently I've feel like I have the fitness to at least not embarrass myself too badly, and I would like to do some TTs around London. I did the Staple Lane hill climb some time ago, but I'd be more interested in flatter 10 milers.
I know I'm supposed to check the british time trials website, but frankly I find it very confusing. And it seems most of them are scattered in all sorts of places across the UK, and I would prefer somewhere within riding/short train journey distance to London (don't own a car).
So can you help me out? What are the most accessible ones I could do?
