I'd obviously prefer to meet in the District or as close as possible, but I know that makes a parking problem for the rest of you. And if it's far enough I wouldn't bike to the start anyway, then I'd need to park too

I haven't tried the north end of RCPark, so your route sounds fine. Only I'd love to do the "loop" backwards (as I posted before), not only because I need more hill practice but once you get to Beach from there you can really hammer as it's flat to downhill in that direction. Also, when you get to the end of the loop that way, the stop sign there in the blocked off area is a good place to stop and regroup. (You'd be on-road the other direction and facing left turns potentially with traffic). I'd also prefer to do the loop at least a couple of times for practice on climbing and descending. From the north, that'd mean doing the flat part before the hill, the hill being the way home. So if after a couple repeats no one wants to do the hill that way, we could regroup at the stop, turn around, and go home as mapped via Beach. Slightly less climbing that way.

Did that make sense?

Hope everyone is having fun this weekend and next. I'm studying for exams
