A Guiseley teenager will attempt his first marathon on Sunday.

Bradford Grammar School sixth former Toby Mountain is running the London Marathon in a bid to raise £2,500 for the Starlight Childrens’ Charity.

Last year Toby, 18, took part in the Great North Run, raising more than £700 for Pancreatic Cancer UK. He has also taken part in the Chevin Chase and a half ironman challenge.

The school held a non-uniform day to give his fundraising target a good start.
