Josh Kerr Shatters 27-Year-Old Mile World Record in London
British runner Josh Kerr breaks world record for mile which stood for 27 years

I shattered the 27-year-old mile world record at the London Stadium, shaving half a second off Hicham El Guerrouj's 1999 mark. Running in a Brooks suit, I crossed the line in 3 minutes 42.66 seconds, fulfilling my 'Project 222' goal and returning the record to British hands for the first time since Roger Bannister.
His win means the mile record is back in British hands after Roger Bannister famously became the first person to run under four minutes in 1954.

What an incredible performance. I've seen a sub-4 mile in person. These guys are absolutely flying. All of them. And he beats the pants off that field.

Unfortunately you can't link directly to the 1 mile results. Scroll down to the table, select "1 Mile Men", then select "Reports", then "Race Analysis" and/or "Race Analysis Graphical". That leads to these two PDFs (not sure these links are stable):

He had a special singlet designed and undoubtedly carbon shoes. Makes you wonder how much raw human potential has progressed vs just having better equipment and track surfaces?

What are the rules around pacers for this kind of thing? Are there separate records for with/without pacers?
