Gar Williams Half Marathon

At $5 to race, what a deal! Low key, we could turn it into a GRC tempo run.

I've done this race 2 out of the last 3 years and for 5 bucks, you typically end up walking away with some socks, a beer mug, and some other DC Road Runner goodies. They changed the location, it used to be down just south of Alexandria in Belle Haven, this year the race is at Carderock Recreation Area (not Park), Carderock, MD
