This unique triathlon includes:
- A 15km cycle through the scenic roads of Snowdonia
- A 3km kayak across the stunning glacial lake, Llyn Padarn
- A 15km hike to the summit of Yr Wyddfa (Snowdon) via the Llanberis Path
This is not your average triathlon. Set against the dramatic Welsh landscape, the Yr Wyddfa Challenge offers a memorable and meaningful way to push yourself physically, enjoy spectacular landscapes all while raising vital funds to support Spread a Smile’s work bringing joy to young patients and their families.
The event is organised by Alder Hey Children’s Charity and, for the first time ever, brings together eight children’s charities – including Spread a Smile – for a shared fundraising challenge. Spread a Smile has been supporting Alder Hey with in-person entertainer hospital visits since December 2024, and we are proud to be taking part in this special event alongside other brilliant children’s charities.
Tasha Mann, Spread a Smile Events Manager says:
“This is such an exciting opportunity and a really special triathlon. The stunning Welsh scenery, the mix of hiking, kayaking and cycling – it’s not your usual challenge event. It’s the perfect plan to have in your 2026 calendar. Do it with a partner, a friend or a colleague, and show what you’re capable of – all while raising vital funds to spread smiles to seriously ill children and their families. Whether you’ve been personally touched by our work or simply believe in the cause, absolutely everyone is welcome – and all abilities are encouraged.”
By taking part, you’ll be joining an incredible community of supporters and helping us bring joy, distraction and moments of magic to children and young people facing serious illness.

“I will remember this weekend for a long time to come. Walking alongside a brilliant group of people, all pushing themselves physically to keep taking the next step, even in the driving rain and dark, was truly inspiring. Knowing the difference our effort will make to families supported by Spread a Smile made it 100% worthwhile.” Laura Walter, Spread a Smile Director of Services
day one with a spring in our step for our first (and highest) peak, Ben Nevis, standing at 1,343 metres tall and the highest mountain in the UK.
“Standing at 978 metres, Scafell Pike is England’s highest peak and welcomed us with much better weather conditions. The scenery was amazing as we approached in the evening sun, driving alongside Wast Water and the view from the top was so lovely. The team made it up and down in a speedy 2 hours 57 minutes, which we were really pleased with. We felt energised and even sprinted the last part of the descent to be sure to get in under three hours!
