>Running 101>If you increase your long run....
what do you do with your other runs during the week? For example, I am currently running about 3 to 3.5 miles 4 times a week. ...
My question is, at what point do I increase the distance of my other runs during the week, and by how much?
Just a note from my own experience -
When I started running 37 years ago I also was doing 3 to 3.5 miles 4 or 5 times a week. It was only 2 or 3 years later when I was doing maybe 25 mpw that I even started thinking about anything like a "long" run compared to the normal daily runs of 5 to 6 miles.
If you are running comfortably and easily and just increase your mileage (or time on feet) by 5% per week, you'll more than double your mpw in 4 months. If you feel like you need to do "long" runs before then, why not just take one of your normal runs and break it up by taking some little walk breaks: instead of just "4 miles" run 1 mile, walk a little bit, and repeat. You might find you can do 6+ miles that way with no problem whatsoever.
