A rare flash entry opening has just gone live for the Cancer Research UK London Winter Run 10K 2027, which returns to Central London on Sunday 21 February 2027 with its popular 10K distance. Inspired by the atmosphere of the London Marathon, the event offers runners a closed road experience through the capital at one of the most vibrant times of the year.

The route winds through Central London on fully closed roads, giving runners uninterrupted access to some of the city’s most recognisable streets. Its flat and flowing nature supports consistent pacing, making it a strong option for those chasing a PB while remaining accessible for runners focused on the experience.

Now a well established fixture, the race continues to attract a broad field thanks to its combination of city centre running and standout atmosphere. From first time 10K runners to experienced club athletes, it offers a balanced mix of performance opportunity and race day energy.

This flash opening is available for a strictly limited time, with entries open only until Tuesday 28 April or until capacity is reached. Demand is expected to be high, with tiered pricing in place, so early sign up gives runners the best chance of securing a place at the lowest cost.

For runners, the race day feel is a major draw. Expect strong crowd support, winter themed entertainment and a lively course that keeps momentum high throughout. It is a course that suits controlled pacing and rewards those who can stay consistent from start to finish and it's a whole lot of winter fun.
