WHAT IS THE DATE OF THE 2025 CANCER RESEARCH UK LONDON WINTER RUN 10K?

After a sell-out in 2024, the Cancer Research UK London Winter Run 10K will return on Sunday 23 February 2025.

FINAL ENTRIES SOLD OUT

After unprecedented demand, the 2025 Cancer Research UK London Winter Run is now at full capacity, as an incredible 25,000 people gear up to conquer the cold at the 10th anniversary edition on Sunday 23rd February.
