Temp 35, DP 34. From Golds Ballston, took Quincy to Custis to W&OD southbound. Took W&OD to turn towards 4 Mile Run near GlenCarlyn, weaved through the construction there, and then rejoined the W&OD north back to the Custis (took alternate Custis) to MM2, where I stopped and did drills and 4 uphill strides. Then took Lincoln to 14th and made my way to Kirkwood, which I took to Wilson. Did a loop around the back of Golds to get the mileage to 10.
