Sabastian Sawe, who became the first person run a marathon in under two hours, will compete at the Berlin Marathon in September, race organisers announced Wednesday.

The 31-year-old Kenyan smashed the previous world record when he ran the London Marathon in 1hr 59min 30sec in April.

Now he will doubtless set his eyes on further lowering his historic time on September 27th at the Berlin Marathon, which is known for producing world records due to its flat course with relatively few corners.

Sawe won the last edition of the Berlin Marathon with a time of 2:02:16 despite heat and humidity in the German capital.

"I am very happy to return to (the Berlin Marathon) this year and to defend my title," Sawe, who won the race last year, said in a statement released by organisers.
