Notes
A good run; saw a group of Kenyans running together. I was tempted to yell to the people behind them: "you can still reel them in!" even to the walkers. But I refrained.
Anyway, I experimented with increasing my turn over to 90 strides per minute. It dropped my pace about a min/mile but my heart rate only went up about four beats per minute. On the other hand, there was an awful lot of down hill during the mile I was messing around with it, so that may be a confounding factor. I'll have to try it again... maybe tomorrow.
