I am attempting to take up a little jogging at the club. I figure it is good as a weight-bearing exercise and it will be good for me next winter when I can't go riding as much as I would like. I will have my own trainer by then, but the trainer isn't as much fun as riding outside/

Eight laps at my club's track = 1 mile. Right now I can JOG two laps for the need for oxygen makes me stop. My body actually feels fine, it is the lungs that are the problem. Last night I did a little walking/running before spinning class and at one point my heart rate was 171 I may have been pushing a little harder than jogging at that point, I can't remember.

I recognize that my body is conditioned for cycling, my heart rate never gets above 150 these days - in a hard spinning class nor outside. Running obviously uses more muscles and so forth...

Is it better to just keep lightly jogging those two laps until they know longer kill me before pushing it further, or should I push it a little further each week regardless? I am unsure the best way to do this as I have never run. I will never be the fastest or best runner out there, but that is ok - it just adds to my cardio choices and I like the jogging-induced breeze in my hair
