Sub 2 Hour Marathon Possible?

Who will be the first human under 2 hours in the marathon? My moneys on Eliud Kipchoge but, i reckon Josdhua Cheptegei the young ugandan runner is one to watch too.

Also have you heard Adidas are trying to copy nike by creating thier own sub2 hour marathon project with runners like Kimetto and Wlison Kipsang.
