Jack Semple Pulling at Kathy Switzer During Race

(Original Caption) The rule that no women shall run in the Boston Athletic Association (BAA) Marathon is being put to a very real test in this photo. Trainer Jack Semple (in street clothes) enters the field of runners to try to pull Kathy Switzer (261) out of the race. Male runners move in to form protective curtain around the female track hopeful, until the protesting trainer is finally wedged out of the race, and the lady is allowed to finish the marathon.
