Ritzov is great but he's not the future of american distance running, this guy already trained like a pro in high-school, not much space for improvement left-i guess he will max out around 13:10/27:20 what is fantastic but no ARs or international medals for him.
Kennedy ran 13:20 off 60mpw(and less in HS) then pushed his training to the max and ran 12:58, Ritz ran 13:20 off 100mpw at altitude, its unrealistic that he has the same improvements post-college as Kennedy,Broe,Meb or Abdi.
Ritzenheins future is the marathon but now that the young ethiopian armada(Sihine,Berhanu,Gebremariam) as well as guys like Tadesse,Wanjiru,the Kenyan-Qataris are already anticipating their Marathon debuts the chance of good european and american 10k runners finding a niche in the Marathon as Baldini or Rey is slimming down.
