Locked out after 10 miles at the high school track

Seized a sunny and warm afternoon to run 10 miles at the high school track at 10:25 minutes per mile, to burn off the party food I consumed. However, I was locked in the field at 4:10 pm and then found a school boy to help me climb over the 12 feet tall fence, which was quite scary for me! I will call the school on Monday for justice! Whomever locked the door could have seen me and asked me to leave before the person locked the door. — checked in to George C. Marshall High School.
