After racing to victory in February in Tokyo in adizero Sub2, Kenyan Wilson Kipsang will again attempt to break the boundaries in distance running in Berlin.
Former men's record holder Wilson Kipsang, last year's victor Kenenisa Bekele and Kipchoge, had made their intentions to beat the record clear with their rapid early pace.
In addition to Adidas athletes, the limited edition Berlin Marathon sneakers can be won by runners who start in Group A and can post a time below 2:50 hours. The only time he has ever lost a 42.2K on the roads was in 2013, when Kipsang ran a then-world record to defeat the great marathoner, who settled for second.
The men's marathon world record lives another day but what a race it was at the Berlin Marathon. Kipsang and Bekele struggled to keep up and eventually dropped out of the race, leaving Kipchoge to battle it out alone with Adola.
They were four seconds outside of world record pace at 34K and continued to slip in the closing stages of the race.
Three-time Olympic champion Bekele, of Ethiopia, can set a huge personal record if he finishes in word record time.
"We haven't finished working out what times the pacemakers are going to aiming for, but it will definitely not be slower than a year ago", said race director Mark Milde. In 2016, he won the London Marathon and the Rio Olympic Marathon.
Once the catch was made, Kipchoge never looked back, storming home in rain for another brilliant win.
The favourite entering the event was Gladys Cherono of Kenya, the only woman in the field who had broken 2:20 entering Sunday.
The long-distance champion from Kenya fought off a surprise challenge from 26-year-old Ethiopian debutant Guye Adola, who finished 14 seconds later in second place.
Ruti Aga of Ethiopia was second in 2:20.41 and Valary Aiyabei of Kenya was third in 2:20.53. Although he had to settle for second, Adola's marathon debut is now the 8th fastest Berlin Marathon time ever ran.
The next Abbott World Marathon Major is the Chicago Marathon on October 8.
