Temp 75, DP 72 - ran from Water Street near Down Dog to Rock Creek, which I took up to Calvert. Walked up Calvert hill (no point pushing it on an easy run the day after hills), then ran Calvert to Columbia to 16th. Took 16th to Kalorama and ran past Mint back to 18th and U, then took Florida to P st to Wisc. FInished with a loop of M to 29th to the towpath, and did some drills when I finished up right below Mint. Used HR limit of 150, though it crawled up in Georgetown.
