Thats not at all what I am implying. Im more than aware the fastest 60m are set en-route to 100m times. What I am implying is that I dont think the athletes have a deliberately different acceleration pattern for 60m and 100m. They are just in better shape when it comes round to racing for 100m due to a multitude of factors. In addition to these factors, a positive tail wind can only help.
Why would they have a different pattern? If it was faster, why not use it in the 60m races, and therefore run faster 60m races?
Im confused by this whole thread - in the 100m (and 60m) dont you just run as hard as you can for as long as you can?
