London Marathon champion Eliud Kipchoge is targeting to improve his personal best of 2 hours and 04:05 minutes either at the Chicago or Berlin Marathon this year.

Kipchoge, who turned down an offer of a place in Kenya’s marathon team for the World Championships due August 22 to 30 in Beijing, China, was non-committal on whether attempting the world record time of 2:02:57, analysts says he could go for it if in good shape.

Berlin Marathon goes down on September 27 with Chicago Marathon coming on October 11, this year.
