London Marathon 2026: Today’s Elite Field, Weather and What Matters
4 Min. Read Time
At 9:40 a.m. local time, the starting gun fires in Blackheath. Sabastian Sawe defends his title, Tigst Assefa aims to retain her world record – and Amanal Petros has the German record of 2:04:03 firmly in his sights. The 2026 TCS London Marathon promises one of the strongest fields in marathon history.

The Men’s Field: Sawe’s Title Defense Against Five World-Class Opponents
Sabastian Sawe arrived in London in 2025 and pulverized the field with a time of 2:02:27. A year later, the situation is even more explosive. The Kenyan has lowered his personal best to 2:02:05 and must fend off five marathon legends. Jacob Kiplimo is switching from track to road – the half-marathon world record holder is making his debut over the full 42.195 kilometers. Joshua Cheptegei, the 2024 Olympic champion over 10,000 meters, is seeking his next milestone on the road.
Tamirat Tola brings experience and world championship titles, while Yomif Kejelcha is also making his marathon debut. The field is so deep that several sub-2:04 times are realistic. The question is not whether it will be fast – but how fast.
The Women’s Field: Four of the Six Fastest Women of All Time at the Start
Tigst Assefa returns as title defender and world record holder. Her mark stands at 2:11:53, set in 2025 also in London. The Ethiopian faces Sifan Hassan, the 2024 Olympic marathon champion who seamlessly switches between track and road. Peres Jepchirchir, world champion and multiple major winner, completes the trio.
Behind them is Joyciline Jepkosgei, who reached a new dimension in Valencia in 2025 with 2:14:00. Four of the six fastest women of all time are running in London today. Whoever wants to hold the world record must adopt a 2:11 pace from the start – and the field forces exactly that.
“Four of the six fastest women of all time are running the 2026 London Marathon.”

German Perspective: Petros Chases His Own Record
Amanal Petros came close to the German record in Berlin in 2025 with 2:04:03. In London, he wants to beat it. The field is running away from him, but that’s not his competition – Petros needs fast pacers, smooth tempo, ideally no abrupt pace changes. The silver medalist of the 2024 World Championships (marathon) did not start in Boston last week – London is his season highlight.
On the British side, there’s also a record attempt: Emile Cairess has Sir Mo Farah’s British marathon record within reach. After finishing fourth in London 2024 and competing for an Olympic medal in Paris, he seeks to break the national best today.
Course: What Tower Bridge, Canary Wharf, and The Mall Force Tactically
The course starts in three waves in Blackheath, leads through Greenwich, over Tower Bridge, through Canary Wharf, and ends on The Mall in front of Buckingham Palace. Sounds linear, but it’s not. The first ten kilometers have a slight downhill slope, which encourages a fast start. This is exactly where hobby runners often get into trouble from kilometer 32 onwards. Tower Bridge at kilometer 21 is mentally the midpoint, technically a short climb that’s often overlooked in live splits. If you run 5 seconds too fast here, you’ll pay for it later.
Canary Wharf between kilometers 30 and 35 is the key zone of the race. Skyscraper canyons, light turbulence, no direct view of the horizon – this section feels longer than it is. Those with structured endurance training have a decisive advantage here: they know what kilometer 32 feels like at marathon pace. The last 5 kilometers through the city center are then pure mental effort.
What Today’s Conditions Mean for the Times
12 to 14 degrees Celsius with a light west wind is a six out of six for marathon weather. The optimum for elites is between 8 and 10 degrees, for hobby runners more like 12 to 15. Today, both groups are close to the ideal window. A west wind means partial tailwind in the second half, which benefits pacers and their protégés. If the technical equipment of the top athletes is suitable, the second main factor is eliminated.
What’s left is the tactical element: how many kilometers will the leading field stay together? In Berlin 2025, the men’s field broke up at kilometer 30, in Chicago 2025 at kilometer 25. London has a tradition of long pace duels driven by pacers who run alongside until kilometer 30. Those looking for a comparison of major marathons find the key data in the endurance profile and the question of how quickly top athletes recover between major marathons in the recovery guide. The answer: shorter than any hobby plan would recommend.
Weather, Start Time, Broadcast
The weather forecast for London predicts 12 to 14 degrees Celsius in the morning, light wind from the west, and high clouds. For marathon conditions, this is close to ideal – cool enough to avoid heat issues, not so cold that muscles become stiff. The elite women start at 9:10 a.m. local time, the elite men at 9:40 a.m. In German time, this means the men’s start is at 10:40 a.m. CEST.
Live broadcast will be on the BBC, and in Germany, via stream from various providers. For the finish line on The Mall, the plan is for the first men to arrive around 11:40 a.m. local time – that’s just before 1 p.m. German time. For those cheering on: endurance training and a good eye for splits pay off. With 5K splits around 14:30, it would be a world record; anything above that would be “only” a very fast London race.
