What would be a formula for determining an estimate of a track runner's speed in comparison to other racers before they race, all others variables being equal, such as leg speed, health, motivation, start reaction time, etc.?(adsbygoogle = window.adsbygoogle || []).push({});

I cannot get a workable idea of the intangibles related to the stride distance variables calculated for a man with 30 inch legs(inseam) and a man with 34 inch legs. I know it is not as simple as the 8.82% difference in leg length translating to a distance increase advantage of that exact amount per stride. I know all variables would never be the same all the time, but a general formula including all the important variables has to be adequate for an estimate that would be much better than guesswork.

Any help here? Thanks.
