Wow, you responded pretty quick!

no offense man, if you want to run, have at it. I ran for many years and am fairly sure that at some point in your life, you will stop too

as far as same workout compared to biking, I would say 5 miles running equals 25 miles biking just based on doing both for a while

to me biking is almost no effort (ducks) compared to running. I get enjoyment from riding and don't really look at it as a workout (even though it might be)
