Notes
1 - 7:26 (hr = 154!)
2 - 7:16 (hr = 160!)
3 - 7:01 (hr = 164!)
for last mile, really upped the pace at the very end, finishing off at 10.5mph (around 5:40 pace) - pretty sure that's the fastest I've ever run on the treadmill (I was on the "fast" treadmill, but still...)
interestingly, this was another instance of a great tempo run (low hr at fast pace) where I was at work earlier in the day, indulging in soda and vending machine food. Coincidence???
Not nearly as hot/humid in gym as during my last tempo run, so maybe that was it?
