The organizers of next year’s landmark double‑header TCS London Marathon have settled the schedule in an unusually playful way – a rock‑paper‑scissors showdown between two former champions. The 2027 edition will be a singular, two‑day extravaganza taking place on April 24 and 25, with an unprecedented 100,000 runners expected to traverse the famed route from Greenwich to Westminster. Initially, the precise allocation of the elite races across the two days was left ambiguous. To bring clarity, the event’s defending men’s champion, Sabastian Sawe – who famously shattered the two‑hour barrier in his victory last season – was asked to help finalize the timetable.
Sawe joined forces with Catherine Debrunner, a four‑time London Marathon winner who set the current women’s wheelchair record in 2023, for a best‑of‑three rock‑paper‑scissors contest that would determine which day each elite competition would be held. Both athletes voiced a preference for Sunday, the traditional marathon day, but the outcome of the simple hand‑gesture game ultimately decided the schedule. Debrunner emerged victorious, securing Sunday, April 25, for the elite women’s and elite women’s wheelchair races.
Consequently, the elite men’s and men’s wheelchair events will kick off the weekend on Saturday, April 24, while the mass‑participation races – open to male, female and non‑binary runners – will be spread across both days, offering a truly inclusive celebration of the sport. Hugh Brasher, chief executive of London Marathon Events, commented on the novelty of the approach: “The 2027 Double TCS London Marathon will be a momentous one‑off event, and Sabastian and Catherine’s battle was an entertaining way to decide which day would host each elite race. We can now look forward to two spectacular days of elite racing, with the men opening the weekend on Saturday April 24 and the women launching the second day on Sunday April 25. The competition may not be quite so friendly when race weekend arrives!
Splitting the elite races will allow us to shine an even brighter spotlight on the extraordinary athletes taking part.” Beyond the novelty, the two‑day format is expected to generate the largest fundraising surge in UK sporting history. Organisers project that more than £150 million will be raised for charitable causes, underscoring the marathon’s reputation as a platform for philanthropy as well as athletic achievement. The expanded schedule gives sponsors, broadcasters, and fans additional opportunities to engage with the event, while also reducing crowd density on any single day – a logistical benefit that could enhance the overall runner experience.
The decision to separate the elite fields also aligns with broader trends in marathon organization. By allocating men’s and women’s elite races to different days, the marathon can provide each group with dedicated media coverage, tailored race‑day atmospheres, and optimal conditions for performance. For instance, weather patterns often vary between Saturday and Sunday, and the split allows race directors to select the most favorable window for each elite field.
Additionally, the staggered schedule offers spectators the chance to witness two distinct peaks of competition, rather than a single, congested marathon day. From a historical perspective, the London Marathon has traditionally been a single‑day event, with both elite and mass participants sharing the same morning. The 2027 double‑marathon concept marks a bold departure, reminiscent of other major city marathons that have experimented with multi‑day formats to accommodate growing participation numbers and to enhance the city’s capacity to host a safe, enjoyable race. The move reflects the event’s adaptability and its commitment to evolving in response to runner demand, public health considerations, and the ever‑expanding charitable landscape.
For the athletes, the split schedule presents unique strategic considerations. Sabastian Sawe, who made headlines by breaking the two‑hour barrier, will now have a day to recover before the next year’s race, potentially influencing his training cycle and race‑day preparation. Catherine Debrunner, already a legend in the wheelchair division, will benefit from a dedicated Sunday spotlight, allowing her performance to be celebrated without the noise of the men’s race. Both athletes have expressed enthusiasm for the format, noting that the friendly competition that determined the schedule added a human touch to the high‑stakes world of elite marathon racing.
In summary, the 2027 Double TCS London Marathon will unfold over two days, with elite men’s and men’s wheelchair races on Saturday, April 24, and elite women’s and women’s wheelchair races on Sunday, April 25. The schedule was decided by a light‑hearted rock‑paper‑scissors duel between Sabastian Sawe and Catherine Debrunner, a decision that has generated buzz and highlighted the marathon’s innovative spirit. With a record‑breaking field of 100,000 participants and a fundraising target exceeding £150 million, the event promises to be a historic moment for athletes, charities, and the city of London alike.
