Couldn't get on with this one and after 50 pages, I'm afraid I'm done. Apologies to my colleague who gave it to me after he'd read it, thinking I'd enjoy it because I enjoy running. Very kind, but I also enjoy good writing and this is not an example of that. Very clunky in expression throughout, lots of talking about logistics, snobby attitudes to some of the places he visited but ultimately I just don't get WHY he decided to spend 2 years of his life and £100k doing this bizarre and colossal challenge which must have made his carbon footprint absolutely gigantic. The actual running seemed like an afterthought, almost an inconvenience, he talked about it so little - I didn't get any sense of passion for the sport or what he got out of it.
So, to sum up, I just don't get it and there are too many other books I want to read to plough through one I think is basically a dud. Just because you can run, doesn't mean you can write well about running.
