Looking for some advice on what my target zone should be when riding.
little background, I'm 52, 5-11 and weigh about 178. I've not been riding the past 12 years or so due to a bad hip. I had hip replacement late last year and now I'm getting back on my bike again. Now my heart rate when riding regularly has always been on the high side so maybe I'm okay.
Yesterday was the first day I've been out on my road bike and I had my HRM on, my average rate was 150bpm and I maxed out at 190 going up a fairly short but very steep hill coming back into our neighborhood. During most of the ride I really wasn't starving for air or did I feel out of breath.
Now if you go by the method of 220-age (52) my max should be 168 and my high end training zone should be around 135 but if I would train at that rate I may as well get off and walk.
Am I endangering myself and should I slow back into it or do I just have a naturally high heart rate? I think in the past I remember maxing out in the hi 180's.
Any advice would be appreciated...
