Residents from Horsforth, Wharfedale and Aireborough are being asked to join a Harry Potter movie star on a fundraising walk this weekend.

Actor Matthew Lewis will be undertaking the fourth Walk of Smiles, to raise money for children with chronic or terminal illnesses, in Rawdon and Horsforth on Saturday.

The actor, who played Neville Longbottom in the hit films, is patron of the Bethany Hare Smile Foundation, which takes its name from the Horsforth teenager who organises the walks.

Bethany has already raised more than £38,000 for charity, and hopes to see as many people as possible joining in this year’s trek, which sets off at 10.30am, from Redbeck Field, Layton Road, Rawdon.

Registration will take place from 9.30am on the day, and free refreshments will be provided for all participants at the start and at the half-way point.

Designed as a fun event for all ages (with children under 14 accompanied), the 5km walk encourages walkers to dress colourfully or in fancy dress and has a circular route which takes in Horsforth Hall Park.

This year’s walk is being held in conjunction with Rawdon Fun Day, which will see a fairground, entertainers, a welly-wanging championship, birds of prey display, trampolines, barbecue set up beside the walk’s starting point.

The fun day will raise money for Bethany’s Smile, Tommy’s – a charity that funds medical research into miscarriage, stillbirth and premature birth – and the Yorkshire Air Ambulance.

Everyone who takes part in the Walk Of Smiles will get free entry to the fun day, as well as a completion certificate signed by Matthew Lewis.

Sponsor forms are available from The Gift Gallery (Yankee Candle Shop), 19A Town Street, Horsforth, or can be downloaded from bethanyssmile.org.

This will be 13-year-old Bethany’s fourth Walk Of Smiles since she began organising big fundraising events at the age of ten.
