The Total Triathlon Almanac-5 is the best training log I have used in my 30 plus years as an endurance athlete and coach. It is actually much more than just a training log. It's a valuable training tool, packed with training and racing tips from Mark Allen, Dave Scott and several other all-time triathlon greats. This information, combined with Tony Svensson's inspiring photos, make the Almanac-5 a great source of motivation as well. This is simply the most comprehensive training logbook and resource available.
