...because that's rational.
5k is about 3.11 miles, so you could run 5k in 30 minutes. You probably already have. If you run 3.11 miles in 30 minutes, that's a little less than 10 minutes a mile. But if you run 5 miles in 45 minutes, that's 9 minutes a mile. Maybe you should try to run 8 or 9 miles in an hour or something. Or try to run 5 miles in 30-35 minutes or something.
