ran at 153bpm today. I think my goal now will be to build slowly from 153 bpm where I am now to 168 bpm. I'll have to find it again, but I recently read about running at 21 strides/15 seconds. this seems to translate to 168 bpm. Who uses strides/15 sec as a measure??!!?? seems cumbersome. maybe to someone it sounds better than 168 bpm.
Nike+iPod says it was 3.8 mi at 12:50/mile. I find the Nike+iPod to be abou 10% too long. I wanted to cal it this past weekend, but the time change beat me up badly. Maps show this to be pi miles. (3.14) Seems sort of cool.
