That is good, if you are already a runner. I have always had better results when I run as well. Just don't go overboard. A mile isn't far.
Many of the old time advice was to incorporate running. Can't remember what though, might have been Brawn, or Keys to Progress or something.
I am not sure what the current thinking is.
But as I said, I get better results when I run as well. And don't overdo it, a lot of runners get runners high and just want to run way too much.
Also some of the routines around here seem to incorporate sprints etc..
And of course, it all depends on what your aims are, anyway.
