8x600m @ < 7:41min/mi (actual splits: 7:42, 7:34, 7:36, 7:38, 7:39, 7:56, 7:58, 7:25), 400m rec. + warm up and cool down. Today I learned that running the reverse loop of Prospect Park is much harder than the usual counterclockwise loop that everyone does. Can you tell where I did my intervals uphill? Chris is convinced I should always run the harder loop going forward.
