I was Nike clocked at a 4.38 going into college but was only good for 40-50 yards. I played in the secondary so the short distance speed was most important. I was never much at long distance runs. When I went through the police academy we had to run 1 3/4 miles in 10 minutes and 5 miles in 50 minutes. I had a terrible gate and struggled more with the 5 mile run.Compare sprinters to most marathoners - sprinters are typically more muscular by a significant margin. And, though I was pretty fast back in my 20's, I've never been fast enough to outrun most NFL running backs, tight ends, etc. in a 100-yard sprint.
