Dr. G passed along a link to me. It is a (free) book (64 page pdf) by Gordon Pirie called Running Fast and Injury Free. He covers all kinds of stuff: diet, weight training, technique, etc. Some really insightful stuff.
This may be old hat to everyone, but there is quite a biit of useful info in it.
Right now his site is down as it seems it has exceeded its daily bandwidth. http://www.gordonpirie.com/
Once the site is back up, it is definitely worth checking out.
