Hey all - here is a clarification i've been thinking about for summer miles.
Last week I had a conversation with a basketball player about using open gyms as running "miles." I have no problem doing this, BUT the only thing you can count is ACTUAL GAMES or SCRIMMAGES where you are running hard up and down that basketball court. Standing around shooting free throws, listening to coach talk, going through plays, are not a good enough workout to call it "running." So, if you are in a game situation, playing hard and running up and down that court HARD, I'd say 10-15 minutes of playing is about a mile.
Consider this - the basketball court is 84 feet long. You'd have to run up and down the court 62, yes SIXTY TWO, times to make one mile of running. And, that's if you go end to end, out of bounds line to out of bounds line. Certainly there is some back and forth movement and it counts too, but I'd say conservatively that 10-15 minute of hard playing is good for one mile.
Soccer players, same thing. Every 10-15 minutes or so of hard playing in a GAME situation can count as one mile of running.
I heard someone said "I was at open gym for 3 hours, that's at least 6 miles." Not even close. Make sure the ONLY thing you count is GAME situations where you're playing hard. 10-15 minutes = 1 mile running.
