I don’t think a lot of people understand that anything around 14 seconds is blazing compared to 90%of all humans. I don’t buy that the median 14 year old boy runs a 14.1 either, those were imformal and widespread studies and relied on the schools to tell them the times so a lot of them would either be self reported times from the students themselves, the teachers setting up the cones estimating a 100m stretch which would likely be more like 80m (seeing as most placees don’t have a reliable track and some don’t even have a track period OR they are just clearly getting yards mixed up with meters.
If we narrow it down to young males:
Average healthy weight young buys run about 16s
Average guys involved in sport or some form of athletic activity = 14-15s
Average sprinters will be anywhere in the 12-13s range (and those ARE the outliers).
If we include the entire population then under 20s will be a massive challenge for most. I am guessing the majority would even need some kind of medical clearance to evemt attempt it.
Under 13s requires some talent and some work.
Under 12 requires outlier talent and some work.
Getting into the 10-11 range is just plain rare amongst humans.
I am talking about wind legal amd FAT times here by the way. The majority of people overestimate their 100m by 2 seconds.
