Lots of fun. I rode with many forum friends. Except for one sub 3 minute mile in SE that must have been all downhill, my fastest splits were chasing the Ngs from Capitol Hill to Hains Point. (I made a Strava segment of that part :p). I tried hard to stay with DCV and family because I’ve been on a few rides with Vince and I know his wheel is a good one to follow. I think he made two wrong turns, which I’m sure is fewer than the vast majority of riders made. Unfortunately, both times were among the rare moments I was ahead of him. When I realized I’d dropped the guy I was following, I back-tracked and dithered, but both times managed to get back on, the second time with KLizotte’s help.
Before Vince caught a flat in SE, we were in a group that included PeteD (who we rode with from the start) and consularrider, but they didn’t realize there was a mechanical and kept going. Luckily the marshall that had a floor pump did notice and turned around to help. Of course we had the ability to inflate bicycle tires, but not as good as he did. 
So we lost Pete and Chris, but as the repair was completed, Klizotte found us, and we managed to stay together most of the rest of the way. I got dropped when a baggie got caught up in my derailleur, and we lost Kathy when she got wedged between two Metro buses (ouch), but we both managed to get back on.
Justin Antos who we saw pulling into rest stops as we were leaving and where the course comes back to itself at Pennsylvania and 38th SE caught us at the AU rest stop and dropped us on University Terrace. He would have passed us sooner but after looking at his GPS track I see he either got horribly lost or decided to add some extra miles to the ride. I’m pretty sure it was the latter.
