Cycling 1:45:00  18.0 mi (5:50 / mi)
Rock creek trail from Kensington to Lake Needwood and back. I have run as far as the Veirs Mill bridge, but I'm pretty sure this is the first time I've been on the section across the bridge to the Norbeck Road underpass.
There were not a lot of people on the trail, a few walkers and cyclists. It had been recently flooded in places, and there was still some standing water. Kind of uneven, with root ridges and other hazards. Not a route you'd want to push the speed on. But a pleasant way to spend a couple hours on the bike, and water fountains every couple of miles.
