Don't rely on what your heart rate is supposed to be w/ regard to your
age. Just because you are 35 doesn't mean your maximum heart rate is the
same as the typical 35 y.o. I'm 40 and have at least a 205 bpm HR max.
(as indicated in the final sprint of a 10K race in Nov.) which is 20 bpm
higher than what I'm "supposed" to have. Find a means of testing your HR
max. so that you can determine the appropriate target ranges for you.
