Hello everyone,

I commute twice a week in Dallas, TX. I use a road bike, I wear breathable cycling clothes and carry a 3 liter camelbak mule and I have a question to experts in this room about commuting in the heat.

Last week I rode up through downtown Dallas to Allen, TX, a hot day, and I mean hot! I rode normally, probably pushing myself when I should not have, drank most of my water supply during the 2-3hour commute.

When I finally made it home my legs felt like spaghetti, and I was fried.. the next day I couldn't ride! I felt lethargic, and my muscles hurt, also a slight headache. To make matters worse the effects have been going for a couple of days, no energy - still not 100%. I rode today, took it easy, made stops and cooled down in the shade for a few minutes.

I believe I might be victim of heat exhaustion, so my question is what tips/suggestions do ya'll have with regard to riding in triple digit temperatures for hours on end?

Thanks in advance!
