The 10km Woolwich Challenge, starting at 11am, provides a family-friendly route with the same lively start and finish hub. All routes have full support, including medical assistance, rest stops, food, drinks, and all finishers receive a London Summer Walk medal, certificate, and a free massage. The London Summer Walk alone has already raised £250,000 for hundreds of charities nationwide. Registrations are still open for the London Summer Walk Ultra Challenge 2026, and sign-ups for 2027 are now available. The London Summer Walk promises to be one of the capital’s standout endurance events of the year.
