Notes
Partly cloudy, mid 70s, and humid (DP in upper 60s) for the RnR Chicago Half Marathon. Clearly I have some work to do based on today's time. After several weeks of easy and lower HR running, it appears that I'm not used to pushing the pace. Lap AHRs were climbing each mile through 6--163, 172, 172, 174, 176 (for 5 and 6), before I slowed it down for 6:50-6:55 pace for miles 7-12 (175, 171, 169, 169, 171, 173). Mile 13 was a 175 AHR (6:27 split, although I suspect that might have been a bit short based on the length of the final .1). Race AHR was 172, with max of 180 (during stretch between miles 5-6). It probably should have been higher than that for a half marathon.
