Winter Enigma Marathons & Half Marathon 2027

The Winter Enigma Marathons & Half Marathon is a small winter running series in Milton Keynes, United Kingdom, taking place over two days in early January. It includes marathon races and a 21.1 km half marathon, allowing participants to choose either the full distance or a shorter option at the same event. The course is a lapped tarmac circuit around Caldecotte Lake. This design simplifies navigation and aids pacing compared to a point-to-point course. The flat, repeatable surface is suitable for runners new to distance events and those aiming for personal bests. All finishers receive a medal.
