This is an MCRRC club race. While it is put on very well, this, in my opinion, is not a half for first-timers. It’s in the heat of summer and the hills on the back half are no joke. A bright spot is the popsicles that are handed out around mile 9 or so.
Casual race through Montgomery County

I like this club. I live in San Francisco. This club is in suburban Washington, D.C. I joined. My father (and brothers, but they are Foreign Service) live out there. I only run a couple of times per year with them. But they are so friendly I wanted to belong.
The prices make it worthwhile too, even if you only show up to a limited number of their events.
This goes along paved roads and paths, next to cornfields, and it’s a casual, mostly flat, reasonably fast course with many more people than I had expected. If I am around for one of their races, I will definitely enter.
