This is a new Ultra Challenge for 2025, set in the stunning Gower Peninsula – the UK’s first Area of Outstanding Natural Beauty and famous for its golden beaches, limestone cliffs, wild moors, ridges, and woodlands. Our basecamp is in the grounds of the historic Penrice Castle, with weekend camping options – and the 100km challenge is a figure of 8 route made up of west & east loops which take in the best of the Peninsula, its history, and its varied and unique landscape. 

It will test spirit & determination but is totally achievable with good preparation and the Ultra Challenge support! With 50km, marathon, 25km, and 10K challenge option as well, and a bar & entertainment at basecamp – this event will be the highlight of the season! You may have to dig deep at times, you’ll meet new friends along the way, and the journey will be unforgettable. As you cross the finish line, you’ll get a big welcome from the cheer squad, a glass of fizz, t-shirt, and a special medal to celebrate your achievement.

Why support Teenage Cancer Trust

A young person talking with a Teenage Cancer Trust nurse

We create world class cancer services for young people in the UK, providing life-changing care and support so young people don’t have to face cancer alone.

Every day, seven young people aged 13-24 hear the words “you have cancer”. They will each need specialised nursing care and support to get them through the toughest times they may have faced.

We’re the only UK charity dedicated to meeting this vital need. By choosing to run for Teenage Cancer Trust, you can help us to reach every young person facing cancer and make a huge difference.

So you know we’re the real deal, these are our registered charity details: 1062559 (England & Wales), SC039757 (Scotland).
