His barrier-breaking run in Vienna did not count as an official world record due to the use of “in and out” pacers and a moving drinks provider.
Kipchoge already holds the world record with his 2:01:39 from winning the Berlin Marathon in September 2018.
“Breaking the two-hour barrier in Vienna was an incredible moment. It showed that no human is limited and that is a belief that continues to drive me on to set new objectives.
“Making history in London is my next target. I am proud that I am currently the only male able-bodied athlete to have won this great race four times and that no one, male or female, has won it more than that.”
The 35-year-old is tied with Ingrid Kristiansen for the most wins in London by an able-bodied athlete. The Norwegian won four London Marathon titles between 1984 and 1988.
Kipchoge’s London titles came in 2015, 2016, 2018 and 2019
