Run at lunch

Bob: ran 7.5 miles at lunch, 1h16:42, 10:15 min/ mile, average hr 148 bpm. felt like running uphill for most of the run, followed by a steep downhill. Mixing a hilly run w/ lower heart rate training is not so fun...again 11:30 min/ miles on the uphills. this is week 4 of low hr running...2 more weeks of this and then I will start to add some higher (160 bpm) intensity runs into the mix.
