CHESTNUT Tree House wants to encourage people of all ages to take on a challenge to mark its 15th anniversary in November.

The hospice says from events and activities, to small actions that make a big difference, there is something for everyone.

It has drawn up a list of 1 ideas:

1. Let 15 people know about its Open Days on October 5 and 6

2. Test your nerve on the 15th birthday abseil at Arundel Castle in September

3. Donate £15

4. Share its social media pages with 15 friends

5. Sign up 15 sponsors (or more) for your next big challenge

6. Give 15 hours through volunteering

7. Chase Santa around the school playground on a 15-lap Reindeer Run

8. Get your heart pumping with 15 runs in the 15th year

9. Invite 15 friends over for a Big Get Together barbeque, cocktail or movie night

10. Shout ‘Geronimo!’ on a 15,000 ft skydive

11. Collect 15 things to donate to your local Chestnut Tree House shop

12. Challenge your workmates to fill up 15 charity bags between you

13. Spread the word by telling 15 friends about Chestnut Tree House

14. Feel lucky with the Superdraw – and sell 15 tickets to your friends

15. Enter a team in the 15th birthday mud run in July.

Linda Perry, director of children’s services, said: “A lot has changed since Her Royal Highness Princess Alexandra officially opened Chestnut Tree House, and we could not have helped the 833 children and families we have over the last 15 years without the help and support of the local community.
