Notes
Ran 1600, 1200, 800, 400, 200 (400r) on the icy cold track at South. Trouble getting a deep breath made this feel really difficult when it should not have. Left hammy a little tight now. Might have overcooked this a little in the cold and with a race on the horizon but splits should have been really manageable. 4:58, 4:43, 2:26, 68, 32.
