While you can do the math I think you made a reading error - neither hill was 1 mile long. In fairness, there is certainly some error in the estimate of my cadence and gearing (my weight is a bit more plus I had a bicycle).Originally Posted by JibberJim .
So 600watts up a 10% hill in 50x20 at 80rpm means the old guy must weigh around 57kg (since the speed is known from the cadence and gearing) and up a hill that is longer than 1 mile (the shorter hill was 1mile) would take 5+ minutes, to produce 600watts for 5 minutes at 57kg gives you a 5 minute power of 10.5 w/kg Or utterly off the charts for any professional cyclist, let alone for an old guy.
"An old guy" you really should get your power meter checked out, it's not been reporting good numbers at all.
But all in all, nice job. You understand what can be done with power numbers.
I have 2 PowerTaps. They seem to agree.
I consider the climb as a 1 minute climb at 300w. I quit my repeats when I take above a minute. The slope was measured by riding up the hill at 250w and watching my speed and then it is just math. (I guess that makes it 30 seconds @ 600w. Not very impressive.)
But again the point was not my ability, but the anger that comes out of the local racers when they think they are racing.
I make no claims about great ability. I get beat by guys in tennis shoes, long pants, and no toe clips.
