Free to Run ★★★★

Excellent documentary focusing on the mainstreaming of running as a sport, with several substrands - the fight for women to be allowed to enter distance races (focusing on Kathrine Switzer, and containing interviews with Switzer and her husband, athlete and running historian Roger Robinson); the evolution of the New York Marathon; the fight for top athletes to be paid; and the fight for freedom from rigid control by the athletics federations.

Lots of interviews and some great historical footage, including unseen footage from the famous Boston Marathon when race director Jock Semple attempted to forcibly remove Switzer from the race.
