If you are going to crown someone fittest you need to include a range of things not just 100m
I would for example beat any Rugby League player by a mile at any distance over a mile and up to a marathon , I am a county standard runner BUT they would beat mean over 100 and at dips etc
A fitness test needs to include a sprint, a long distance race, some strength work etc
I think Superstars did have an 800m or 1500m by memory but its not long enough as a fitness test
