Last year Kelvin Kiptum did 2.00.35 and Sifan Hassan 2:13.44. Hassan goes on to win Gold in Paris in the marathon, KIptum, sadly no longer with us, but he was literally less than 1 second per km or just over 1 min per mile off of going sub 2.
Both world records. Hopefully those racing have another great day. If you can please post some stories/reports on here.
