(Long and Less Long) Runs- 1/15/07 to 1/21/07

Not sure what you meant by this? 160 is a normal working heart rate for me, I can still breathe through my nose at 160. If its too high then I'm snookered!

Nice going on the 18K!

It's all about long slow distance. Slow being the operative part in this situation. Usually recommended that when you are increasing distance on the long run, you should keep your heart rate low. This means less chance of injury and better use of the aerobic energy system for fuel. In effect, you are training to bias your body towards fat as fuel. This increases endurance and helps to prevent hitting the wall. Keeping your heart rate low also forces you to work on efficiency of running.

160 isn't a bad HR to run at, it just depends on goals etc. If you can still breathe through your nose, you're golden. Where your aerobic zone falls depends on age, fitness and especially anaerobic threshold.
