wutz in the electrolyte? I think the 3 things should be sodium; potassium and magnesium. when i go on long rides I salt my water; take a full potassium supplement pill, and a 1/2 pill of magnesium. I also soak in a hot bath after the ride with a generous amount of epsom salt. I understand your muscles absorb the magnesium through the skin tissue. too much magnesium can cause loose stools, so caution with dosage. are you getting enough rest and massage between rides? overtraining?
