ELI5 Is 20km/hr the top pace a human can run at distance?
Watching world athletics championship and was wondering..if marathon runners can run at approx 20km/hr for 2 hours why is pace for the 5000m only about 21-23 km hour (13-14 mins) ? Given the huge difference in distance I would expect that for the much shorter distance they could run faster than that. At what distance does human speed start to exponentially taper off? #education
