The Novices Guide to Long Course Triathlon.
A starting point for those about to take on the challenge, the author takes you through his experiences and what works for him.
This was a practical guide toward Ironman-level triathlons and is filled with good advice for any level. I'm a newbie at the Sprint and Olympic level distances so it's good to get advice from a clearly superb triathlete and marathoner. Definitely worth a read.
