I took the best splits from the top 7 runners and added them together and got 59:53.51 proving sub 1 hour possible. https://imgur.com/a/S6YHXOG

While sub one hour is possible, we won’t see it for a while.

Also remember that not every runner splits at the same points in the run

There u go, spreadsheet to go with it

felas,

I don't think it's possible

for me
