Mine is 3 minutes. Running from my apartment in Jasper to my job downtown 20 years ago.
Back in high school we were running 2–3 miles /class period during gym class. But that’s 50 years ago.
I doubt I could do a quarter mile today.
3 to 4 miles when I was in high school.
4 times around a track in HS.
Didn’t we just have this question, but in distance? Probably something like 15 minutes, followed by a break and another 15 minutes, if I recall correctly. Did that a fair number of times in high school.
