Assuming you're single, this is your opportunity to make a connection with the young, cute, single female teacher.
After following this pattern of running to and from work, make sure to casually let said cute female teacher what you're doing.
Make sure to be seen by her leaving your classroom or the school in your running clothes. She will be intrigued.
One afternoon a few weeks into the school year, casually mention that you have a lot of paperwork to bring home on that afternoon's run home. She'll offer you a ride and bingo, you're all set.
