I like Sport tracks a lot. I find I usually compare mileage by month and year mostly. Always seems to report a slightly different mileage than Garmin TC. Don't know why.
Thanks INTEGRATE. I usually try and get in 10 to 15 miles on the way to work, but on those mornings when I want to sleep, I just head straight to work. Looks like I can try backing off the effort once or twice and recover on the 5 mile ride.
I have noticed lately (past year) that the heart rate has droped off quite a bit. For years, my heart rate ran regularly in the 160 to 170 range while riding. It is now in te 140 to 150 range with the legs feeling the same level of effort. I am assuming that I crossed some fitness plateau and that is not just 44 years catching up with me. I should say that I have only been seriously cycling since probably 2006 and my mileage has gone up quite a bit the past couple of years.
Thanks again.
