Stanwick Lakes Winter Santa Run 2026

Runners in Santa suits line up at Stanwick Lakes for a winter race day on purpose-built tracks inside a nature reserve near Wellingborough, Northamptonshire. The programme includes 5K, 10K, and half marathon options, suitable for first-time recreational runners as well as those chasing a personal best. The half marathon uses a two-lap, clockwise, multi-terrain lakeside route, with the start listed at NN9 6GY. Ultramarathon.org organises the race, and the half marathon field is capped at 420 places, with registration closing once it sells out. The Santa suits provide the event's festive hook, while the lakeside reserve setting keeps the course more interesting than a standard road loop.
