Hatfield House, Hertfordshire
Willow’s annual 10K event is a great race for beginners and experienced runners or walkers going through the picturesque grounds of Hatfield House. Including our 5K race and our 1.8km Family Fun Run.
Run or walk as our marshals cheer you along, and this year we’ve lined up some extra entertainment to keep you going!
The Willow 10K is a fundraising event and we encourage everyone to raise as much as they can. An online fundraising page will be set up for you as part of your registration.
