In ‘The Lore of Running’ by Tim Noakes you’ll find various tables which have used different statistical methods(!) to predict the progression of performances over time and interestingly…ultimate performances for 100m to marathon. If my memory serves me well, the ultimate performance prediction for 400m was 39secs

I put the human limit in all sprints at .1 of a second - at least until the start rules change.
