As I pondered why I noted my time this AM, I realized that knowing it will be useful. I will be traveling a bit over the next few weeks to locales where I will not have access to a track and, in a few instances, my own transportation (to clock mileage). Therefore, knowing how long it takes me to run a certain distance I can estimate how far I've traveled. Eureka!
So today I did 1.75 m in about 17 minutes. On Thursday I have to do 1.5 miles. I'll time myself again. That way I can estimate how far I traveled on those days when I'm out of town.
