Willow 10k 2026

The Willow 10K is a charity running event at Hatfield House in Hertfordshire, featuring a 10K, a 5K, and a 1.8km Family Fun Run. The family race starts first, followed by the 10K and 5K later in the morning. Both timed races use chip timing. It accommodates a wide range of participants: beginners, experienced runners, and walkers. The 10K has a 2-hour cutoff, and the 5K has a 1 hour 15-minute cutoff. The route crosses the grounds of Hatfield House, making the setting as much a draw as the distance. The Willow Foundation organises the event as a fundraiser, and participants are encouraged to raise money via an online page set up during registration. Marshals provide support along the course, additional entertainment may be present, and all finishers receive a medal. Results from multiple past editions indicate it is a regular local fixture.
