London’s race is on.
Run wild. A record 1.33M people applied to run the 2027 TCS London Marathon, up 18% YoY and more than double the 578K who entered in 2024. Reaching the masses, roughly one in every 60 UK adults wants a race bib.
Max capacity. The 2026 edition saw 59K+ finishers, the largest marathon field ever. Expanding the base, 40%+ of this year’s applicants are first-timers, meaning new runners are fueling growth.
New cool. More than a race, London Marathon week blends sport, culture, and commerce.
In 2026 alone, brands generated ~$60M in media impact value, with adidas capturing ~$11M on Sabastian Sawe’s record victory. Setting up shop, On, New Balance, and Gymshark opened community-driven London flagships in recent years — hosting shakeouts, product drops, and events to convert runners into customers.
Big business. Last year’s TCS London Marathon generated an estimated £226M across the UK, including £68M in London alone. Stateside, New York City’s running economy is nearing $1B, with race-related spending flowing into hotels, restaurants, and retail.
Punchline: In London and beyond, running is much as a hobby as an economic and social engine, turning participation into a city-wide movement.
