It's achievable by people with a reasonable fitness level who are prepared to train beforehand. The more you train, the more you’ll enjoy it.

It’s a great incentive to get fit and work different muscles, knowing you’re raising funds for an excellent cause at the same time.

cyclists

As the route is on-road, mountain bikes are not recommended. However, if you have trained on it and are confident you can complete the course you are more than welcome to use it. .

Stage 1 - Bike 39 miles

At dawn, you'll set off from the event base on a 39-mile bike ride that begins with a ride to the coast.

From there you will follow the River Seiont as it flows out of Llyn Padarn and joins the sea at Caernarfon with its historic royal fortress.

Here the route rides along coastal roads before returning inland with a stunning backdrop of Snowdonia ahead of the final push that brings you back towards Llanberis ready for the next phase of the challenge!

Stage 2 - Hike 9 miles

Once you've donned your hiking boots it's time to embark on a 9-mile return walk along the Llanberis path.

This route offers a nice gradual climb that follows the iconic Snowdon Mountain Railway, before your final ascent to the summit of Yr Wyddfa (Snowdon). Sitting at 1,085m above sea level, Yr Wyddfa is the highest mountain in Wales and England that offers unforgettable views of the Welsh countryside and Llyn Padarn below where the water phase of the challenge will take place.

Stage 3 - Paddle 2 miles

Lifejackets on, it's now time to take on the final stage of the challenge!

In either a kayak or rafted canoes, your team will work together to complete a 2-mile circular route on the waters of Llyn Padarn, a lake nestled amidst some of Eryri's (Snowdonia's) most spectacular scenery, including the imposing Llanberis Slate Quarry.

RACE FOR A REASON
Race for children like Jack

Jack was born extremely prematurely at 25 weeks, weighing just 1lb 15oz.

He needed oxygen, help with his breathing and feeding tubes to survive. He suffered a collapsed lung and brain bleeds and contracted the potentially deadly bowel infection necrotising enterocolitis. Jack went on to endure many more serious health problems and spent four and a half months in hospital fighting to survive before he was finally allowed home. Jack's mum is so grateful for the work that Action does:

It is so important that studies like those funded by Action Medical Research are done. Without research, we wouldn’t have medical advances, and Jack probably wouldn’t be here.

The event was brilliantly ran by the organisation and everyone was very friendly. The challenge itself was tough and definitely required more training than I expected. Really good day and excited for 2025. Chris P

From the moment we registered the updates and support was fantastic, from fundraising ideas to event info and guidance. On the day all the marshals were so friendly and motivational, I personally thank each and everyone for this. The food was all on point and the safety was never in doubt, brilliant event and I highly recommend. Vicki E

Beautiful setting and a stunning cycle course and kayak. Fuelling before, during and after the event was delicious and plentiful. Event space well organised and maintained during the event. Really friendly and helpful volunteers. Event was on the right side of challenging. Thank you to all the team for a really memorable day. Jenny H

Well organised by super friendly people. Loved the bike ride and the canoe. The climb was incredibly hard but we got there and back. Surprised and pleased to get a trophy for fastest mixed 4 person group. Not bad for our first event like this. Matthew K

Absolutely sensational event. Exceptional organisation with a fantastic team . Also a big fan that they had thought so much about sustainability, from the pre comms through to the choice of medals. Brilliant. Jo C

I can highly recommend getting involved with an Action event, not only for participation in a personally challenging event, but also to support a very deserved charity. I will definitely participate again in the future!

We had a fantastic weekend, and loved the novelty of doing 3 different disciplines. What took the event from being really good to being really special was the atmosphere created by the Action staff and the other participants who were all incredible!
