What's under foot, though, might have been a factor when Elaine Thompson-Herah broke a 33-year-old Olympic record in the women's 100m. Thompson-Herah beat the Olympic Record by 0.01 seconds to run it in10:61. It's shaping up as a fast track surface at Olympic Stadium. Runners are certainly on track to setting personal, Olympic and possibly even world-record times over the next week at the Tokyo Games. Thompson-Herah also has a theory on fast times after running 10.61 seconds to break the Olympic mark of the late Florence Griffith Joyner.
