I followed your nutrition advice for a recent 110km training ride and it worked like a charm! Then a few days later, I did a 32km run with lots of hills. I stuck to your calorie plan and did not cramp or tire at all. It’s the first time I’ve ever run more than 10km!

Excited to tackle my next IRONMAN!

After the wheels fell off in my first IRONMAN race Taren suggested my issue wasn’t fitness, but nutritional. He suggested I read this book and adapt what I could to my training. Having followed the book's advice I now set out on BRICK runs after long bike rides feeling strong.

As I challenge myself to reach my full athletic potential, I once again turn to Taren for nutrition advice. Taren's latest book, Triathlon Nutrition Foundations takes all of the guess work out proper nutrition for training, racing, and living the life of an endurance athlete. Thanks for more rock solid advice, Taren!
