London is loaded once again as World #1 Kipchoge goes up against a stacked field that includes the past two world record holders (Kimetto and Kipsang), world champ Ghirmay Ghebreslassie, NYC champ Biwott and the great Kenenisa Bekele. It also has huge Olympic qualifying implications for Kenya + Great Britain. Set your alarms. This one is worth getting up for (5:00 a.m. ET start on Sunday).

OH BABY WHAT A RACE!!! This one reads almost like fantasy track. Something has to give as it features the fastest man in history Geoffrey Mutai, the world record holder Wilson Kipsang, the defending champ Tsegaye Kebede, past champ Emmanuel Mutai, the Olympic and world champ Stephen Kiprotich, and the debuts of Mo Farah and Ibrahim Jeilan. We try to break it down for you. *IAAF: "Best Ever" Field

Geoffrey Kipsang is a name you had better remember. The 2011 World XC junior champ got his first global senior title with an impressive 59:07 win without a rabbit as he led 30,000 runners to the finish line in the first time ever that the World Half Marathon Champs were a mass participation race.  Tiny Eritrea got gold in the team competition.
