Australian-based Shaun Englehart will battle the gruelling 26.2 miles in a bid to secure cash for young people living with the illness, as part of the new partnership between the student-friendly travel agency and the charity.

On top of Shaun’s challenge, STA is also giving travellers the opportunity to donate £1 to the trust when they book a holiday in one of its stores.

Donations secured will go towards funding nurses, youth support coordinators, and running specialist hospital units to help sufferers aged 13-24.

As well as helping those in the UK, money will also be used to aid patients in Australia, New Zealand and the US.

Upon launching the new campaign, STA Travel chief executive officer John Constable said: “We are thrilled to be supporting Teenage Cancer Trust. The sad reality is that cancer affects many young people, and as the world’s largest youth-based travel company it touches many of our customers and people worldwide.

“We send more than two million young people on life-changing trips every year, but there are thousands that miss out due to illness. The work of the organisations that we’ve aligned with is vital and we’re delighted to launch this world first global partnership.”

Siobhan Dunn, chief executive at Teenage Cancer Trust in the UK, added: “To be part of a world-first global fundraising partnership is extremely exciting and everyone at Teenage Cancer Trust is really looking forward to working with STA Travel and being part of its vision to support teenagers with cancer across the world.”
