Following a sold-out 10th-anniversary edition in 2025, the Cancer Research UK London Winter Run returns on Sunday, 15th February 2026. The CRUK London Winter Run 2025 broke all previous records as 19,820 runners finished in 2:21:29.

CRUK has informed runABC South that demand for the 2026 event has been unprecedented. With more than 24,000 runners already registered, fewer than 2,000 places remain to reach the event's strict capacity.

If you want to join the UK's largest 10K and help raise another £1 million for Cancer Research UK, two options remain. You can register your interest for an exclusive invitation sent on Wednesday, 7th January 2026, by leaving your details to receive the entry link. Entries will be strictly sold on a first-come, first-served basis.

Alternatively, if you can't wait until 7th January, you can enter today by committing to raise £175 for Cancer Research UK as an Exclusive Fundraiser. As an Exclusive Fundraiser, you'll receive a discounted entry, an extra-special bonus medal, and enjoy access to the VIP fundraiser marquee to celebrate in style once you complete your 10K.

Your fundraising will support Cancer Research UK’s vital work and the charity’s vision of a world where everybody lives longer, better lives, free from the fear of cancer. Last year's event raised over £880,000 to help stop cancer in its tracks.

Cancer Research UK London Winter Run features include live music performances, larger-than-life winter characters, and world-famous landmarks such as St. Paul’s Cathedral. Over 100,000 people have run the iconic central London course to date, raising over £7 million.

Last year's HOKA-sponsored winners were Kris Jones (Swansea Harriers, 29:22 PB) and Emma Pallant-Browne (Aldershot, Farnham & District AC, 34:32). Over 400 people ran the course in less than 40 minutes.
