Eliud Kipchoge’s aim at the BMW BERLIN-MARATHON on September 16 this year is clear cut: to break his personal best. Given that he is the Olympic champion and acknowledged to be the number one for the distance in recent years, this suggests the 33-year-old Kenyan is ready to produce something special. His best is currently 2:03:05, set in winning the 2016 Virgin Money London Marathon. This was eight seconds slower than the world record which remains in the possession of his compatriot Dennis Kimetto (2:02:57), when winning the 2014 race in Berlin. Kipchoge’s mental as well as physical prowess has suggested for some time that the world record is within his reach.
