Wilson Kipsang just ran 2:03:13 in Berlin. He says he wants his world record back. We think a course record (2:05:42) is more reasonable. But it should be exciting nonetheless and the best part about it is you don't have to get up early to enjoy. Live Saturday night during prime-time.

Chicago champ/Tokyo CR holder Chumba takes on '12 Olympic medalists Stephen Kiprotich and Abel Kirui, plus Amsterdam champ Bernard Kipyego, Berlin runner-up Eliud Kiptanui and Japan's top marathoner, Masato Imai (2:07:39 pb). Eritrea's Teklemariam Medhin (two-time World XC medalist) makes his debut.

Ethiopians Endeshaw Negesse and Birhane Dibaba got the Major marathon season underway with their first major wins as Stephen Kiprotich was a hero in second, Tariku Bekele bombed in his debut, Japanese twitter went nuts over the marathon, and Lauren Kleppin took a shot at greatness but bombed. We break it down.
