RW UK really lacks a bit in sophistication, the magazine is unfortunately all about FLM and mainstream running.
There are a few more interesting running related books I would add:
Pre America's Greatest Running Legend - I guess this is a classic
Marla Runyan: No finish line - Shows whatever disability you have there is always a way
Running with the Legends - Various chapters about elite runners, Bill Rodgers, Uta Pippig, Greta Weitz, Kip Keino, etc.
Train Hard, Win Easy - Great insight into Kenyan training, includes lots of training schedules
