London Winter Walk Ultra Challenge

24th January 2026 - 25th January 2026

Start New Year on the right foot!

A great event to wrap up and walk off the Christmas and New Year celebrations; maybe kick start a new fitness regime – and to fundraise for Winston’s Wish!

There are Full Marathon, Half Marathon and 10km distance options – and an accessible ‘Family Fun 5K’ on the Sunday. All routes start and finish at The Oval Cricket Ground, and take in highlights of the Thames, its historic bridges, and many of the Capital’s landmarks.

Sign up as a team, or as an individual and families are welcome. There’s rest stops with snacks and drinks, a special medal, and hot food back at the finish before you head home.

EARLY BIRD DEAL As Winston’s Wish are an official partner on this event, you get a 50% discount on the ‘Full Sponsorship’ registration fee when signing up to support us and a free bobble hat!
