About the Event

Conquer a marathon your own way at the unique Colworth Marathon Challenge, from June 26th to 28th, 2026. This distinctive event deconstructs the classic 26.2 miles into three separate races over three days on the beautiful, private Colworth Estate in North Bedfordshire. Test your versatility across varied terrains: a Friday evening 5-mile multi-terrain race with family fun, a Saturday midday 8.1-mile cross-country challenge, and a Sunday 13.1-mile half marathon finale. Choose to run one, two, or embrace the ultimate test of cumulative endurance by completing the full trilogy. With free on-site camping and a supportive community atmosphere organized by Colworth Striders, it’s a perfect 2026 multi-day running event for those seeking a sociable yet demanding alternative to a traditional single-day marathon. Build your medal collection and your resilience across an unforgettable weekend.
