Run the Willow 10k for the Willow Foundation's 10,000th Special Day and make every step count towards supporting seriously ill young adults.

Now in its fifth year, the Willow 10k promises to be a great day for all. Open to beginners and experienced runners alike, this year features a new route, starting in full view of stunning Hatfield House - and there's a new 10K walkers option too.

There'll be a fun warm-up, music playing on the course, refreshments and a physio on hand to ease any aches and pains (for a small donation). Plus a free kids' 100-metre dash for all budding young athletes.

Family and friends are welcome to join the cheering teams and everyone will have access to Hatfield House's Stable Yard, with its lovely shops and superb cafe.

Whether you choose to run or walk the route, every step and penny raised in sponsorship will make a positive difference to the lives of 16 to 40 year olds living with life-threatening illness.

Entry fee is £16.50 for adults and £12.50 for under 18s.

Last year's event sold out fast, so register today!
