I ride in a very warm and often humid climate. Rides of 40 miles or more, especially with lots of climbing, can be a recipe for cramping so supplementing with electrolytes is a good preventative measure. I've tried Hammer Products as well but I like these better because they have caffeine and a shot of B vitamins. I personally like the light boost from the caffeine on a long ride. The taste of this stuff is not too overpowering and there's no strong, fake sweetener, which can be hard to take when you're doing hard efforts. I use this stuff in at least one of my two bottles for all my rides of more than 30 or 40 miles. I also distance paddle outrigger canoe and SUP on the ocean and it works great for that too.
