Gu Energy Labs sent me some of their products to review a while back. To read the review, visit http://midwesttriathlon.blogspot.com/2010/05/gu-review.html. I love to hear about others' experiences with gear and nutrition. Let me know what you think of Gu products or what you use instead. Brendan Brazier, in his Thrive Diet book, has a gel recipe based on dates and coconut oil. Sounds funky but I'm going to give it a try.
