Assuming the reported min/mile pace is correct

Ah I see, thanks. I completely skipped over the min/mile paces, because they're completely useless to me. I'm a runner first and foremost, and that pretty much requires working in kilometres even if I didn't use kilometres for my day-to-day, since all common races are measured in kilometres (from the 100 m sprint up to the 42.195 km marathon).

The article seems to be based on a report from December of last year. Unfortunately I can't find a way to explore the underlying data in greater detail.
