The sub two-hour marathon is the last great barrier of modern athletics.

Eliud Kipchoge, the world’s greatest marathon runner, will attempt to break the two-hour barrier in the INEOS 1.59 Challenge, a special marathon being run between late September and early October 2019.

The event will be supported and managed by INEOS. A London venue is being considered.

"Running the fastest ever marathon time of 2:00:25 was the proudest moment of my career", said Kipchoge. "To get another chance to break the magical two-hour mark is incredibly exciting. I always say that no human is limited and I know that it is possible for me to break this barrier".

On 6th May, 1964, Sir Roger Bannister achieved what many believed to be impossible and ran the world's first sub-four-minute mile at the Iffley Road track in Oxford. That historic achievement remains one of the most iconic events in the history of sport.

On its 65th anniversary, Eliud Kipchoge, the greatest marathon runner of all time, announced his plan to break the legendary two-hour barrier.

Eliud came close to making history in his first attempt to go sub-two when he clocked 2:00.25 in a specially created event (not recognised as an official world record) at Monza, Italy in May 2017.

On 17th September, 2018, he then took 1 minute 18 seconds off the official world record in an awe-inspiring performance at the Berlin Marathon, clocking 2:01:39.

Now, following a historic fourth London Marathon win, the world number one believes he is ready to break the two-hour barrier in the INEOS 1.59 Challenge.

He added: "I learnt a lot from my previous attempt and I truly believe that I can go 26 seconds faster than I did in Monza two years ago. It gives me great pride to accept the challenge presented by INEOS. I am very excited about the months of good preparation to come and to show the world that when you focus on your goal, when you work hard and when you believe in yourself, anything is possible".

Eliud will be supported by Patrick Sang, his inspirational long-term coach, and the team that has led him throughout his successful career who will do all they can during the preparatory phase to ensure that nothing is left to chance.

"As Eliud showed in Monza, when he came within touching distance of achieving what many had previously thought impossible, he is a truly special athlete with incredible levels of mental resolve", explained Sang. "Throughout his dazzling marathon career he has pushed the event to a new stratosphere and with the right preparation, I believe he has the ability to make history".

The venue for the INEOS 1:59 Challenge is currently being decided, with a number of options that offer a flat looped circuit being investigated for the event which is planned for late September or early October 2019.

A major marketing campaign will publicise the run and live coverage will be broadcast across the world, both on traditional and digital channels. Tens of thousands of spectators are expected to attend.

The INEOS 1:59 Challenge is supported by INEOS, one of the world's largest manufacturing companies, which also sponsors the children's running charities, GO Run For Fun and The Daily Mile.

Sir Jim Ratcliffe, Founder and Chairman of INEOS, said: "Eliud Kipchoge is the greatest ever marathon runner and the only athlete in the world who has any chance of beating the two-hour time. We are going to give him every support and hopefully witness sporting history".
