I've been using the Hammer Endurolytes also and they seem to help me feel better by the end of the ride. I've been stopping off @the tennis court restroom at the local high school and discovered that its air conditioned so that has really helped me to cool off. I can't do 40-50 miles in this heat without stopping and washing off with cold water and cooling my body down. We sometimes stop at the local coffee shop and grab a cold frappacino which helps us survive the heat/humidity. I've learned also when we have the heat advisory that its just plain miserable to ride unless I take precautions and cool off halfway. I'm becoming more 'delicate or high maintenance' in this heat :)
