I'd give this 7 stars if allowed. Great stuff. It's indeed a little book, and organized around 250 tips (to help you run farther, faster, more consistently, injury-free, and a miscellaneous section), so you'd think that each would be basically a bumper sticker aphorism a la "train don't strain". But actually, Scott Douglas is such a great writer that he packs a convincing, concise essay into each tip.
Some are well-known points (use a running log; strive for even pace in races), some perhaps less well-known but not likely controversial (treadmills are good for hill repeats; get up as early as you need to in order to run before a plane trip), others contrarian (run with the wind at your back in first half; you don't need to replace shoes after fixed number of miles; ignore 10% rule for weekly mileage increase), but all are informed by the author's 30+ years as a dedicated runner and his exceptional career as a running journalist and author.
Like all of the author's books, chapters, blog entries, etc., there's a lot of humor here (on the edgy, sarcastic side, not the yuk-yuk "isn't that word 'fartlek' funny to say?" side), but also sincerity and passion. I'm a middle-aged paper pusher who's been running since age 14, and have a lot in common with the author (though I was never nearly as fast) -- we even know several of the same people pretty well -- so maybe his views resonate with me more than they might with everyone, but if you have any interest in running and especially performance running (trying to race as well as you can, whatever that level may be), I'd encourage you to read this one.
My personal favorite = tip 245 "nobody likes a martyr": "the quickest way to get others to not take interest in your running is to always be bitching about it. Yes, sometimes it's tiring, or the weather's bad, or you're slower than you were a few years ago....sorry, but almost nobody cares......Running is a gift we give ourselves because we realize it makes our lives better. Try to be a good presenter of that gift."
