Gee. Haven't seen Kejecha, Aregawi, Barega, Gebrigwet, Wale ,etc etc move to a marathon yet. I wonder why? Maybe cuz you go there when you know you're not fast enough on the track? No one in the race could "try". They knew they couldnt beat Jakob no matter what they did. They learned that last year when Jakob jogged a 12:48 with a redlined Gebrigwet not able to do anything. Face it, what you're seeing is a once in a lifetime talent. Absolutely unbeatable
