The Kenyan is the fourth fastest marathon runner ever with a personal best of 2:03:13. In what is probably the strongest men’s elite field ever assembled in the history of Germany’s biggest spring marathon five men feature personal bests of sub 2:06. The field includes the Olympic Champion from London 2012, Stephen Kiprotich. However there are half a dozen runners in the race with faster personal bests than the Ugandan.
