Race walkers achieve high walking speeds by altering their gait kinematics. In 2015, Yusuke Suzuki of Japan set the world record for the men’s 20-km racewalk with a time of 1:16:36. What was Yusuke’s average speed in m/s and his Froude number at this speed, assuming his leg length is 0.9 m? Why is it possible for him to "walk" with a Froude number greater than 1?
