Kenyan marathon star Sabastian Sawe is set to return to the streets of London in 2027 to defend the title he claimed in unprecedented fashion a year earlier.

The reigning TCS London Marathon champion and marathon world-record holder has been confirmed for the 2027 TCS London Marathon, scheduled to take place on Saturday, April 24, and Sunday, April 25.

Sawe made history in the British capital in April 2026 when he clocked an astonishing 1:59:30, becoming the first man to break the two-hour barrier in a record-eligible marathon. His extraordinary performance also saw him improve the previous world record by 65 seconds.

Now, the Kenyan superstar will return to the scene of his greatest marathon achievement with the chance to defend his London crown and add another memorable chapter to his remarkable career.

However, the 2027 edition will be unlike any London Marathon that has come before it.

For the first time, the iconic event will be held across a two-day marathon weekend, with a huge field of 100,000 participants expected to take part. The historic format will see the elite and mass-participation races distributed across Saturday and Sunday.

Remarkably, the decision over which elite athletes would compete on each day was settled in one of the most unusual ways imaginable — through a game of rock, paper, scissors.

Sawe faced Catherine Debrunner, the women's wheelchair world-record holder, in a contest to determine who would claim the traditional Sunday slot.

Debrunner won the showdown, meaning Sawe and the elite men's field will headline the action on Saturday, April 24, while the elite women's and women's wheelchair races will take centre stage on Sunday, April 25.

Saturday's programme will feature the Elite Men's Open, Men's Wheelchair and Men's Good for Age races, while Sunday's schedule will include the Elite Women's Open, Women's Wheelchair and Women's Championship races.

For Sawe, though, the novelty surrounding the 2027 event will eventually give way to the familiar challenge of covering 26.2 miles through the streets of London.

He will arrive as the defending champion and marathon world-record holder, carrying the weight of history after delivering one of the most extraordinary performances ever seen over the marathon distance.

On April 24, 2027, the spotlight will once again fall on the Kenyan superstar as Sawe begins his bid to retain his London Marathon crown and create another unforgettable moment on one of the world's most famous marathon courses. 

The 2027 TCS London Marathon has found a remarkably unconventional way to settle one of its biggest questions — with a game of rock, paper, scissors.

Kenyan marathon star Sabastian Sawe and Swiss wheelchair champion Catherine Debrunner, the reigning London Marathon champions in their respective races, went head-to-head in a contest overseen by an official Guinness World Records adjudicator.

Debrunner emerged victorious, securing Sunday, April 25, 2027, for the elite women’s and women’s wheelchair races. As a result, the elite men’s and men’s wheelchair races will open the historic weekend on Saturday, April 24.

The unusual showdown has also earned its place in the record books, with Guinness World Records recognising it as the first elite marathon race start ever decided by a game of rock, paper, scissors.

The decision adds another memorable chapter to what will already be an extraordinary edition of the London Marathon. For 2027 only, the race will be staged across two days, creating the Double TCS London Marathon, with around 100,000 participants expected to take part across the weekend.

Sawe enters the story as one of the defining figures of the 2026 London Marathon. The Kenyan made history by clocking 1:59:30, becoming the first athlete to run a sub-two-hour marathon in a record-eligible competitive race.

Debrunner, meanwhile, is a four-time London Marathon wheelchair champion, making her one of the most successful athletes in the event’s history. Her victory over Sawe means the women’s elite and women’s wheelchair races will retain the traditional Sunday spotlight.

The 2026 London Marathon also produced another landmark performance on the same course, with Ethiopia’s Tigst Assefa setting a women’s-only marathon world record.

The unprecedented two-day format was introduced following extraordinary demand for places. A record 1.33 million people applied for the 2027 London Marathon ballot, surpassing the previous record for any marathon.

With approximately 100,000 runners expected to finish on The Mall over the weekend — close to twice the size of the 2026 field — London is preparing for one of the biggest marathon weekends ever staged.

London Marathon Events chief executive Hugh Brasher added a playful warning after the rock-paper-scissors showdown, suggesting that while Sawe and Debrunner could settle the schedule with a game, the atmosphere would be considerably more competitive once the racing begins.

And so, before the first elite athlete has even reached the start line, the 2027 London Marathon has already made history — with its schedule decided not by the clock, but by rock, paper, scissors.

The TCS London Marathon is preparing to make history in 2027, with the world-famous race set to become a two-day event for the first time.

The landmark edition will take place on Saturday, April 24, and Sunday, April 25, 2027, bringing together an unprecedented 100,000 participants across the weekend in a one-off expansion of one of the world's most prestigious marathons.

Known as the 2027 Double TCS London Marathon, the historic weekend will give thousands more runners the opportunity to experience the legendary course from Greenwich to Westminster, while elite athletes and mass participants share the spotlight across two days.

The decision to introduce the two-day format follows extraordinary demand for places. More than 1.33 million people entered the ballot for the 2027 marathon, underlining the enormous global appeal of the London Marathon.

DOUBLE BILL! 

For the first time in the event's history, the elite programme will be spread across two days, creating a unique weekend of world-class marathon racing.

SATURDAY, APRIL 24

1. Elite Men's Wheelchair

2. Elite Men

3. Men's Championships and Good For Age

Saturday will put the spotlight on the men's competition, with the elite men's wheelchair race and elite men's marathon forming the centrepiece of the opening day. Men's Championship and Good For Age runners will also take to the iconic London course.

SUNDAY, APRIL 25

1. Elite Women's Wheelchair

2. Elite Women

3. Women's Championships and Good For Age

Sunday will then belong to the women's field, with the elite women's wheelchair and elite women's marathon races followed by the Women's Championships and Good For Age categories.

The two-day arrangement will create a completely different atmosphere around the London Marathon, allowing the world's leading athletes and thousands of amateur runners to share the spotlight across an extraordinary weekend.

A Marathon Weekend Like No Other

Despite the expanded format, the event will retain the character that has made the London Marathon one of the world's most recognisable road races.

Runners will once again take on the iconic route through the streets of the British capital, beginning in the Greenwich area before making their way towards the famous finish in central London.

The 2027 edition will also provide an enormous platform for spectators, charities, volunteers and running communities from across the globe to become part of a historic occasion.

More Than Just A Race

The 2027 Double is expected to become much more than a marathon. It will be a huge celebration of running, charity and London communities, bringing together recreational runners, elite athletes, volunteers, spectators and supporters from around the world.

The London Marathon has long been recognised as one of the world's major fundraising events, and the expanded 2027 edition is expected to create even greater opportunities for charities and community organisations to raise money.

Organisers have projected that the 2027 Double could generate more than £150 million for good causes, while also delivering a significant economic and social contribution to the United Kingdom.

The wider celebrations will also include the TCS Mini London Marathon, ensuring that young runners have their own opportunity to be part of this historic weekend.

One Historic Weekend, One Iconic Race

Although the 2027 edition will look very different from previous London Marathons, the two-day format is planned as a one-off change for 2027.

With 100,000 participants, two days of elite competition and a mass field representing runners from around the world, the 2027 TCS London Marathon is set to become one of the most extraordinary editions in the event's history.

From world-class wheelchair athletes and elite marathoners to Championship competitors, Good For Age runners and thousands of recreational participants, London will become the centre of the global running world for one unforgettable weekend.

For more than 1.3 million hopeful runners around the world, the wait is finally over.

Today, 1,338,544 applicants are discovering whether they have secured a coveted place in the 2027 TCS London Marathon, as ballot result emails are sent out to every entrant. It marks one of the most eagerly anticipated days in the global running calendar, with this year's ballot rewriting the history books before a single runner has even crossed the start line.

The unprecedented number of applications has set a new world record for marathon ballot entries, highlighting the ever-growing appeal of one of the world's most iconic road races. Despite organizers expanding the event to accommodate a record-breaking 100,000 participants, demand was still extraordinary, leaving the chances of success at approximately one in 13.

The 2027 edition will stand apart from every previous London Marathon. To celebrate the event on an unprecedented scale, organizers will stage the race across two days—Saturday, April 24, and Sunday, April 25, 2027—creating what has been named The Double. Around 45,000 runners will take to the streets on Saturday, while 55,000 will compete on Sunday, making it the largest marathon event ever staged.

Unlike previous years, every ballot entrant was automatically considered for both race days. Successful applicants will therefore receive confirmation not only that they have earned a place but also which day they will run the famous 26.2-mile route from Greenwich to Westminster.

London Marathon Events Chief Executive Hugh Brasher described the occasion as a landmark moment for the sport.

"The 2027 Double TCS London Marathon will be a weekend of celebration like no other in history. This is a once-in-a-lifetime opportunity for 100,000 people to take part across the two days," Brasher said.

While many runners will be celebrating today's life-changing email, over a million others will inevitably miss out through the ballot. However, the draw is far from the only route into the race.

Charity entries remain available, and for this unique 2027 edition, selected charities will also offer places on the Saturday race. The National Autistic Society has been named the event's official Charity of the Year. Additional opportunities are available through Good for Age qualification, affiliated running clubs, and the MyWay virtual marathon, allowing participants to complete the marathon distance anywhere in the world during the same weekend.

Another major announcement is still to come. Organizers have yet to reveal whether the elite men's and women's races, along with the Championship and Good for Age fields, will be staged on Saturday or Sunday. The decision is expected to attract significant attention following this year's historic London Marathon, which witnessed the first officially ratified sub-two-hour marathon performance, further elevating the race's global prestige.

For the fortunate 100,000 receiving positive news today, however, those details can wait. Their focus now shifts from anticipation to preparation as they begin the journey toward becoming part of one of the most historic marathon weekends the sport has ever seen.

The countdown to the 2027 TCS London Marathon has officially begun, and for those holding a successful ballot email, history awaits on the streets of London.
