Thank you for posting this Emily. I have always wondered. I enjoy just one cup of coffee in the morning, but before rides some have said that it dehydrates you. I have not found that to happen to me, however, find like everyday, perform at my best with just that one cup. I will know "really" enjoy drinking my cup of coffee before my ride.

Just to touch a bit on what others have mentioned, my Grandmother is 98 and has and still does drink coffee, black, throughout the day and has no heart or bone problems. My dh Grandmother lived to 100, drank coffe and expresso (with sambuca sp?) everynight and had not heart or bone problems. Maybe it depends on the individual and how their body handles. Maybe it is a hereditary thing. hmmmm
