Conner Many is getting there...just give him time.He is actually improving steadily.Just a few more races and he will be right there on top.Its not easy to overcome the mental barrier.
John Korir was in excellent shape.He averaged 250km per week during his build up.He upped his milage from around 210km a week in the build up for Chicago.
Many folks don't know that Cyprian Kotut is Martin Lel's younger brother.He is super talented just like Martin but just hasn't hit the kind of high mileage Martin was doing yet.
So ,the 3 that actually beat Mantz were exceptional athletes today.
Give Mantz time....he will get there.
