Yesterday I rode for about an hour, my heart rate was about 180 for the whole time. I was curious what others heart rates were.

Heart rates vary from person to person. The old (and generally inacurate) formula to figure up what your maximum heart rate should be is to take 220 and subtract your age. The variance in that formula's answer for you and your actual maximum heart rate can be ludicrous. I'm 25 so my max heart rate should be 195, but I've tested myself and seen it at 206, and I suspect it could go a few beats higher.

For most people, 180 either is or is about to be lactate threshold, the point where your heart can no longer pump fast enough to pass blood through your muscles in sufficient supply to carry away all the lactic acid your muscles are producing during anerobic resperation. Some people have maximum heart rates of 175, so their lactate thresholds will be different. My guess is you were hammering that whole hour if your heart rate was 180 or more the whole time. If you train so close to your maximun heart rate all the time, you'll get terribly overtrained in no time.

A perfect read on the subject is a book called Heart Monitor Training for the Compleat Idiot by John L. Parker, Jr. Another good book that addresses heart rate training in more detail for cyclists is The Cyclist Training Bible by Joe Friel. You can find both of them at
