Eliud Kipchoge is set to headline the Berlin Marathon, seeking to break the world record.
## What's at Stake?
Kipchoge, 32, has a personal best of 2:03:05, set at the 2015 London Marathon.
He won the Olympic marathon in Rio de Janeiro in 2:08:44, beating Feyisa Lilesa by 70 seconds.
## His Recent Performance
In May, Kipchoge fell 25 seconds shy of completing the first-ever two-hour marathon at the Breaking2 project in Monza, Italy.
His time doesn't count for record-keeping purposes due to the use of pacers throughout the race.
Eric Gillis, a Canadian marathon runner, recalls Kipchoge's move towards the later stages of the Rio Olympic marathon, saying "really no one could keep up with him".
## The Competition
Kipchoge will face strong competition at the Berlin Marathon, including Kenenisa Bekele and Wilson Kipsang.
The three runners will compete for the first time in the same Berlin Marathon, the fourth of the calendar year's Abbott World Marathon Majors.
Reid Coolsaet, a two-time Olympian, believes Kipchoge is "a bit ahead of the other guys" despite all three having long careers and knowing what it takes to succeed.
## The Record
Dennis Kimetto's 2014 world record of 2:02:57 is the target for Kipchoge, who many believe has the potential to shatter it.
On September 22, 2017, Kipchoge was preparing to take on the challenge, with the Berlin Marathon set to be live streamed at CBCSports.ca at 3:15 a.m. ET.
Kipchoge's past achievements include Olympic bronze in 2004 and silver in 2008, as well as a win at the 2013 Berlin Marathon.
At 19, he defeated Kenenisa Bekele and Hicham El Guerrouj to win the men's 5,000 metres at the world championships in Paris.
"I think Breaking2 was an example of his greatness," said Eric Gillis, "not for only how fast he ran, but for him to handle the pressure of the all-or-nothing-type of environment."
Kipchoge switched to road running after missing the 2012 London Olympics and has since become one of the most dominant marathon runners in the world.
The Berlin Marathon will be a key test of his abilities, with a strong field and a chance to make history.
"They've all had long careers, good marathons and know what they need to do to succeed," said Reid Coolsaet.
Kipchoge's experience and skill make him a strong contender for the world record.
The stage is set for an exciting race, with Kipchoge facing off against some of the best marathon runners in the world.
