some of the guys I coached youth sports with would sometimes run with the kids
40 ... 60 ... even 100 yd dash
and of course they would often pull up limping lol
at one point - later years - my youngest kid ran 4.85 40 ... low 7 60 ...
that might not seem fast - especially compared to the large number of top athletes that run 4.4 40’s etc - but 4.85 40 is still honkin compared to the avg joe
one kid from his high school class ran a 10.27 100m this past year while competing in college ... he is a world class athlete / future Olympic hopeful
For 60meters you'd have to be under 7 seconds (consistently) to be competitive in college at the national leve, down around 6.60 sec. for world-class consideration. .
10.27 isn't that fast for the 100m by national or world class standards. Here in California we have a few 10.2 runners each year at the high school level. The competitors in the USA Olympic Trials need to have qualifying time of under 10.05 seconds (minimum), and almost all of the competitors that get into the trials have times under 10.00 seconds. In all the sprint races (100m, 200m, 400m, 110m hurdles and 400m hurdles) its so tough and competitive that (as the saying goes)
the toughest part of getting to the Olympics is considered just qualifying for the USA team.
