The fastest marathoners in the world are competing on one of the fastest courses on the planet. Records are likely to fall come Sunday in Berlin.

Eliud Kipchoge’s aim on Sunday is to break his personal best and attack the world record while Wilson Kipsang is equally primed for a record chase. So far the score in their Berlin rivalry stands level at 1-1. Kipsang took an early lead by beating Kipchoge here in 2013 but the Olympic champion hit back to win the Berlin title last year.

The strongest women’s field in the history of the BMW BERLIN-MARATHON will line up for the 45th edition on Sunday, including perhaps the greatest female long distance runner of all time, Tirunesh Dibaba. Among the Ethiopian’s rivals will be last year’s winner, Kenya’s Gladys Cherono and her compatriot Edna Kiplagat, a double World champion. Four women will be competing who have run under 2:20 which remains the major yardstick of excellence for the women’s marathon. It is clearly the strongest women’s field ever assembled in the German-speaking world.

FloTrack will stream the event for select countries outside the U.S. with Australia being one of them (requires a $29.99 subscription). The race will begin at 5:15 pm Sunday, Sydney time on 16 September.
