No, i'm not familiar with the 4-minute mile and its history. I just did a quick search on it and it's being able to run a mile in under 4 minutes (as the name implies). It was first done by Roger Bannister in 1954. It has been done many times since, but it's like a standard benchmark these days.
I'm not sure how that answers my question. Maybe I missed some important part of the history of the 4-minute mile.
