Goose your quote above intrigues me. What evidence is this based on? As far as I’m aware running races on the moon have been pretty scarce, and who is to say that athletes might not be able to cover the distance much faster than on earth as far few strides would be required? It might not look like running as we are used to but then again 10yrs ago I doubt many of us thought that an athlete would be running inside 9.70sec with less than 41 strides either. The line that “the biggest influence on 100m speed is gravity” needs to be backed up with evidence please…
