Notes
Was supposed to do two 4 mile tempos at 6:35-40 and 6:30-35. The first one (miles 4-7) averaged 6:33. The second one was 2 miles at 6:31, around 2 min. rest, then 1.5 miles first at 6:32 then creeping above 6:40. I was warm the whole time and stupidly wore a short-sleeved instead of a sleeveless shirt. Drank more water than before, which seemed to help hamstring tightness. That's not what stopped me - I was just tired, partly from the heat. Still a good run.
