There's more to running a marathon than buying new trainers and jogging around your local park a few times. A lot more.
Mr Taylor gives you the marathon low down, with humour and humility, giving the impression that if he can do it, so can anyone. Which, judging by the description of his previous lifestyle, is absolutely spot on. So long as the wannabe marathon runner is dedicated, realistic and gets themselves fit, of course.
Don't even contemplate crossing the starting line without reading this book. Or read this book and enjoy an adventure at someone else's expense without having to leave the comfort of your own sofa.
