Gainsborough 10k & Half Marathon November 2026

The Gainsborough 10k & Half Marathon is a November road-running event based at Sturgate Airfield near Gainsborough in Lincolnshire. The half marathon starts first in the morning, with the 10K setting off shortly after, so runners can choose between a shorter race and a full half marathon on the same day. Both races use road-closed, single-lap routes on flat roads, which makes the event straightforward for first-timers and useful for runners chasing an even pace. The route leaves the airfield for quiet country roads, then passes open farmland and village stretches before coming back to a village finish. Every kilometre is marked with distance flags, and marshals are posted around the course to guide runners and cheer them in. Entry includes chip timing, free race photos, post-race goodies, and a themed medal, so the setup feels practical without being overcomplicated.
