Our Story


  • Finding out that GU includes only those beneficial amino acids in their endurance products, but not all of the other useless ones in a complete protein made me realize that the science behind their passion was real. I will also admit that when I tasted Chocolate Smoothie Recovery drink, that sealed the deal.

  • My first bonk was during the Double Dipsea in 2009, on the return back to Stinson. The next year, I dropped 2 GU’s at the turnaround, ate them, and never felt a dip in my energy levels. After the race, I knew I’d found something that worked for me and haven’t used anything else since.

  • GU played an important role during one of my proudest accomplishments early in my ultra-running career, my Grand Canyon Rim-Rim-Rim Fastest Known Time. After that there was never any doubt GU Energy would take care of me on any adventure I tackled.” “Chocolate Smoothie Recovery Drink Mix is my go-to after a hard effort or long run. Almost always used in a Vitamix concoction with soy milk, yogurt, banana, nuts and cinnamon.

  • In 2000, two other climbers and I completed the Slovak Direct route on Mount McKinley (Denali) in 60 hours. The fastest ascent before that had been 7 days. We relied almost entirely on GU Energy Gel, literally climbing from one Gel, feeling that we were getting close to the bonk, then doing another Gel. It got us up 70% faster than anyone before us. That record still stands 14 years later and I’ve been using GU Energy products religiously ever since. I use them training and on my big climbs. When people ask me how I do those big climbs so quickly, I always tell them that nutrition planning is big part. Thanks GU!
