(edit: I wrote this a while ago, and it sat waiting for an image of my ride home for about a month. downloaded about two months worth of crap off the garmin last night, so this post finally gets published. pretend it's April 21st...)
What went right.
The next 1.5b laps were spent trying to get Ezra Mullen off my wheel. On the second lap I managed to find, and finish, the bottle I lost on the first lap. With my hydration strategy back on track, and a pro feeder handing me bottles, I was able to attack through the feedzone going into the last lap. I got a little gap on Ezra, and kept my foot on the gas to cross the finish line 1:55 ahead of him.
I'm really fast at the end of races, I should try harder in the first 66%.
...and my drivetrain is defunct.
