Yesterday I was on a climbing ride with about 3300ft of climbing, there was also high winds in the area (approx 25-35 mph gusts).
About 1/3 of the way into the climb, I began getting cramps in my quads. While I was stopping for a rest and a stretch, a cycling in our group stopped to assist me. He advised that I should probably be downing about 6 Endurolytes. Up to that point, I had taken 2 Endurolytes before the ride started. And two more before he advised me I should take more.
I was able to continue riding after some snacks and stretching. I continued riding another 3rd of the climb, but after a particularly grueling section while fighting a massive headwind, my legs went into some major cramping and I fell over while pushing a measly 4 mph. The very experienced rider I was climbing with advised me to continue popping Endurolytes. Within two hours I probably dosed about 10 capsules.
During this whole ordeal, I had also consumed 2 bottles that contained Gu Electrolyte powder.
I've been following the instructions on the Endurolyte bottle but that seems insufficient compared to what riders were telling me during my ride yesterday.
So my question to you is, is it "normal" to be taking so many Endurolytes during a very strenuous ascent? Should I pop more of these before my ride to ensure I don't go into electrolyte deficit in the first place?
