The London Marathon is set to make history in 2027 by transforming into a two-day event for the first time, accommodating a record-breaking 100,000 runners over the weekend of April 24-25. This temporary expansion is being implemented in response to an overwhelming demand, with more than 1.3 million individuals having entered the public ballot. Despite the increase in participant slots, the probability of securing a place remains under 10% due to the immense interest.
The expanded event is expected to become the largest fundraising event in UK sporting history, with projections estimating that over £150 million will be raised for various charities. Additionally, the marathon is anticipated to generate approximately £400 million in social and economic benefits, further emphasizing its significance beyond just a sporting event.
During the weekend, the marathon will feature a variety of races. The first day will spotlight the elite women, elite female para-athletes, championship, and “Good for Age” women’s races, alongside a mass participation race involving nearly 50,000 runners. The second day will be headlined by the elite men’s race and will also include another extensive mass participation event.
Participants will only be allowed to compete on one of the two days, with the results of the ballot expected to be announced in early July. This special two-day format is confirmed as a unique celebration, and it is anticipated that the London Marathon will revert to its traditional single-day schedule in subsequent years.
