Having been probably the laziest person on the planet for the last 15 years of my life, i decided last year that i had to set myself a challenge to lose some weight and achieve something i thought i'd never do - so i thought what better than enter the Great North Run! Like most here, i picked this book because it had great reviews - and i have to say i now know why! Its sympathetic to novice runners, really informative on all the main topics, amazing photos and all in all a great book to have by your bed or on the kitchen table. I don't want to tempt fate but so far i am virtually injury free, LOVING my running (theres something i thought i'd never say) and on target to finish the GNR without walking. I can't wait.
If you, like me, are a nervy newbie to the world of running and are thinking of running a half or full marathon - i'd strongly suggest you buy this book. I'd advise you to get others too, for variation more than anything, but out of all the books i have on running, this is the one i have used as my bible and dog eared the most.
