Let me try a post from my half iron distance race today. I think the only good thing was it confirmed that I'm relatively aero . . .
1. Average Power - 183W
2. Average Speed - 24.1mph/2:19.02 Garmin split, 2:19.?? official split (results not posted yet).
3. Distance - 56mi (Patriot Half Iron in Freetown, Mass - fast course)
4. Rider Weight - 129lbs
5. Bike - Dimond Brilliant w/ Zipp disc and Enve front, TriRig aerobar, Vittoria Corsa Speed
General commentary - I've only done two races on the Dimond, both relatively remarkable splits compared to my wattage IMO. Added the Vittoria today for the first time. I did this same race in 2011 on a Trek Speed concept at 186W in 2:28, though I was running 808s w/ lower quality tires. Wattage should have been >= 200 today, but just had a terrible race in all three sports for whatever reason. Being aero somewhat saved the day, otherwise my performance would have been even more embarrassing.
