Kate, Laurah, Barrie, Kim, Vicki, Kathryn, Graham and Bob are taking part in the Wolf Run to raise money for Kate's son Tristan to have an operation to help him walk.

This operation will reduce the stiffness in Tristan's legs caused by cerebral palsy and make it easy for him to walk. This operation used to be covered on the NHS but it no longer is. We are raising money to get him to America for this life-changing operation.

They need as much money as possible to get him the op and pay for intensive physiotherapy for the 2 years afterwards. £10 will pay for a session horse riding/ equine therapy. £50 will pay for one hours physiotherapy.

Please give generously to his little boy. He was born 9 weeks prematurely in 2009 and spent 5 weeks in Neonatal Intensive Care. He has a little brother called Ioan ("yo-un") and we'd love to see them running about together in the garden in future.

Thank you for your support. You can find out the full story at www.justgiving.com/tristanstarget
