I mentioned in my last post that one of my favourite running books is Running for Mortals by John Bingham. It's a great introduction to running! He (and his co-author, Coach Jenny) write in a very approachable way. The programs they suggest are great for beginners (run/walk method) and they provide lots of motivation and advice. Much of what I learned from them formed the basis of my whole approach to running. It took me some time—and some injuries—to get there. But, I'd have to say that Bingham gives great, foundational advice for runners at all levels.
While I love his book, I find I'm at the point where I need a new running book. I'm looking for one with reliable training plans for 10Ks through to marathons, as well as training advice and ideas. I've taken quite a few out from the library, but haven't found any I like.
