Ive had a thought to compile a few lists of people who are at either ends of breaking certain barriers in different ways in events. The usual sub 10, sub 20, sub 45 ie ie but i want to know whos lets say the tallest and smallest man to break 10, the youngest to first break the barrier and the oldest to ever break the barrier. the first man to break 10 and the last man to break 10 for the first time.
off hand i would guess lerone clarke is the smallest and usain bolt is the tallest
you see how this works feel free to add your own " want to knows" and events
