How do you measure your runs: by mileage or time?

I've gone back to running by miles but leaving the watch home.

I run by footstrike count.

Dont you know if you go for an easy 30 min. you've covered approx 4 miles?

I never understood why people get hung up in that stuff. Same with HR over pace. Either way you are measuring the effort you are putting forth during the workout.

I've been using time of late, and have found I enjoy my runs more. I'm not racing them all the time.

By height.

time is how the elites do it,
