The Triathlete’s Training Diary, 2nd Ed.

Your Ultimate Tool for Faster, Stronger Racing

By Joe Friel


The Triathlete’s Training Diary from Joe Friel is designed specifically for triathletes to record and analyze their swim, bike, and run training, diet and nutrition, and recovery.


A perfect companion to any triathlon training program, The Triathlete’s Training Diary offers an ideal way for you to plan, record, and better understand your workouts and performance. With undated pages for use any time of the year, this diary offers plenty of space for all the objective and subjective performance metrics you might want to track in a smart format that’s been carefully designed, tested, and refined by Joe Friel, the top coach in the sport of triathlon.

The Triathlete’s Training Diary is wirebound to lay flat and flips easily so you can look up past workouts or settle your pre-race nerves by proving to yourself that you’ve done the work. This paper workout log is simple to use, never requires a login or password, and can be completely customized to meet your needs for any triathlon training schedule. This physical record of your workouts will reveal insights that don’t display on an online dashboard.
