I've never ridden so hard or fast in my life. It was a great time, and I learned a lot about my (and my bike's) limits, dodging the guy who's being carted off in an ambulance, and of course how to yield to the right as the group laps me.
I wasn't even really ever on the back, so I'm not sure I can say I was thrown off it. I had trouble with my cleat, and by the time I had cranked it up to 26mph, I realized the group had notched it up above 30. I stayed within 20 feet or so for almost a lap, but just couldn't grab on. After that it was all downhill. I maintained a personal best solo speed for 30 minutes, but it wasn't anywhere near what the group was doing.
The announcer said I had "heart". Nice crowd. Next time, I'll be in better shape and they won't have to cheer so hard
