One African American male who holds a T&F world record is Michael Johnson in the 400m dash.
I don't know about the record, but I run the 400m for high school track. My PR is 63 seconds, but there are other girls on my 4 x 4 team who run 56's and they broke the school record. To get anywhere near a scholarship, you have to run at least a 57 for the 400m. It sounds easy but don't under estimate it until you try to run that time.
Michael Johnson currently holds the world record for the 400m at 43.18 seconds.
