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!
