It's funny how most of the people on this website are quick to judge! Joshua Cheptegei is one hell of a runner! The first time, I saw him was back in 2016 in Carlsbad. Listen to the interview towards the end of the video, you will see how confident this young man is.

Y'all remember what happened to him in Uganda (World Cross country Kampala)when he crushed everybody but ran out of gas in the last 600m.
In fact, this is not the first time he tried to break the 15km W.best! Last year he came short but we all knew with better pacing he would get it!

Yes he sometimes go train with the best group in the world in Kenya. Global sports communication is the one managing him along with all the big names you may know: Kipchoge, Kamworor, Bekele, Abel Kirui, Rono, Augustine Choge, Ayana, Sifan, Dibaba, Florence Kiplagat, amongst many others.
If you see the logo (Nike NN), chances are it's somebody managed by Global Sports Communication.
What you should ask yourselves is why so many fast races are often ran in Netherlands! The terrain is one answer but Jos Hermens is the other! He is a great duch agent and he negotiate big money for his stable!
As for Joshua, he is been very consistent and I am not surprised of his achievements! Maybe one who doesn't follow the sport may think like who is this ''kenyan '' that just ran the fastest 15km ever out of no where? The simple fact to ask the question is answer enough!
