A Harry Potter Studio Tour could be up for grabs for those taking part in a May Bank Holiday fun run.

Those lacing up their running shoes for the Watford 10K in Cassiobury Park on May 6 could win a trip to Warner Bros. Studios Leavesden - while also contributing much needed funds to Watford Mencap, a charity supporting those with learning disabilities.

Junior runners who raise over £50 in sponsorship fees will be entered into a draw for a Harry Potter family ticket, while adult runners will be eligible for a place in this year's Royal Parks Half Marathon.

This year’s Cassiobury Park race is being held in partnership with Watford Harriers and Active Training World – and those taking part may choose between 1K, 3K and 10K courses, catering to all abilities.

The parent of a child being helped by Watford Mencap said: “Without the support of Watford Mencap in our community, children and families would struggle to cope and lead a normal happy life. Their time and compassion know no boundaries and bring hope and solace to those blessed with disabled children."
