My powertap reads the correct values on the screen, but once i download, my total ride time is usually about 10 minutes greater than what the screen/unit says. I assume that this is from getting off the bike, as I do about twice during a 2 hour training ride. Whatever, I’m cool with that. But what really gets me going is the speed. My average speed today, for instance, on the screen was 14.2 mi/h. on my computer it is 9 mi/h. total distance was like 10 miles less than what I did. Cadence, I think due to the whole time thing, is also deflated. average cadence that is. What the problem is?
On a side note, the PT software sucks. Cyclingpeaks worth the 75$? Can I put my HR data from my polar on there too?
thanks
