I became addicted to Hammer Nutrition's product family last year. I now use their Perpetuem for rides >2 hours, and a variety of their supplements. Did my first century ride last October, and 57 miles the next day. Felt great both days. Slowed down part way through the second day because we broke a wheel, otherwise riding strong all the way through.
