Ran a 4 miler this morning in Central Park. Splits w elevation details below:
Mile 1: 6:32 (net elevation gain 62 ft)
Mile 2: 6:17 (net elevation loss -43 ft)
Mile 3: 6:31 (net elevation gain 15 ft lots of hills)
Mile 4: 5:58 (net elevation loss -29 ft)
I felt awful on the uphills and super fast on the downhills. I obviously left too much in the tank on mile 3 based on my last mile.
