Just W/KG or am I an aero brick?
I did a duathlon yesterday. 12 mile ride tucked between 2x2mile runs. The bike was 3 laps and each lap had two short (under 45 seconds), punchy climbs and one longer descent. Looking at my buddies data vs mine, it seems like I should have gone faster on the bike looking at power numbers:
Friend: 165lbs, 23 mph ave speed, 240 watts average power, 267 normalized power
Me: 190 lbs, 21.7 mph ave speed, 310 watt average power, 304 normalized power
Understanding the contributing differences/margins of error in the PM's (his a Pioneer/mine P1's), does that look all that out of whack to any of you? I am really just looking for excuses to say it's not the weight so I can keep eating like a monster. The Norm Watt/KG is basically even between the two.

Who ran better?
Also his power meter could be a lot more accurate than the P1s. So you are likely seeing an inflated value there.
Overall, I would say he's probably a better cyclist than you (obviously because he went faster) because he hit the hills harder and applied less power on the downs, as implied by the greater variability in AP to NP - I dont know where your numbers came from, AP should be less than NP. Watts matter more on the uphill than they do coming down.
Anyway, I think he ran 5:30's the first 2 miles then probably 5:45-5:50's the last two. There is a huge hill to run up on each run which brought me to a crawl both times. That said, I was quite surprised and happy with 6:30's the first two and 6:54's the second two. I was a distant third overall and believe it or not he was a distant second overall because an all-american level cross country runner (and phenomenal college aged triathlete) showed up and cruised sub 5:00's then put almost 2 minutes into him on the bike despite having only ridden a bike 3 times since December.
My fit was by Jim Manton at ERO. Think his fit is from Steimenz. Hopefully it's that my fit is good and his is great - otherwise we both need refunds. I have no doubt he rode it smarter because he is really good usually at pacing and I am really good at .erg mode!
Anyway, appears to be not too out of the ordinary.
I was actually assuming his power meter must be reading low as well and he just told me he only had his left crank arm reading during the race. That likely explains a big part of it because I am sure he is right leg dominant (like most) and therefore was actually putting down more than 2x his left.
As for AP/NP - I am usually pretty close between the two. Not sure what that means - is that not ideal?
Anyway, thanks for the feedback. I am a poor cyclist (and could stand to lose some weight). Got it.
Re his power meter, even if he is right dominant, there is little chance it's more than a 5% difference, so I wouldn't expect real numbers to be more than about 10-12W higher than what he got.
