The chart that u/givethemnothing posted really helps paint a wider picture, the record for 1500m W50 is 5:05.xx. Dude just missed record pace by 2 seconds. Conversely, the M50 is 4:18.xx. He's still 30 seconds behind the top female 1500m, though. Still, I wouldn't be surprised to see this guy hold the division record sometime in his career as a W50.
