I put this ACL injury, research, and recovery page together for him. For daily news on running you can not beat the Runners' World Daily page. It is published new five days a week and they do keep older articles archived as well. I like it a lot. The site also helps know how hard to train and can make race comparisons.
Few things are more fun than trail running.
Run the planet Runners go through many shoes. I am currently running in the Adidas SuperNova. I highly recommend going to a specialty running shoe store where you will get service and know-how that you do not get at a department store. Their site also include a race calendar. I am sort of a member of the Dead Runners Society .
