Help us unite Wales against cancer and join #TeamCRW for the ultimate ultra trail endurance race
Starting and finishing at the foot of this iconic mountain, your challenge is to ascend and descend Yr Wyddfa as many times as possible in 24 hours.
For solo runners, this is the ultimate endurance challenge requiring great physical and mental stamina. The current record is 8 laps - can you beat it?
Snowdon 24 can also be entered as a pair or team (up to 5). Taking part in a relay format, it's a fantastic and unique way for people to come together for 24 hours as friends, colleagues or teammates and work towards a shared goal. Every person in the team contributes, whether they make one ascent or ten.
Your support will help bring better treatments closer to home for patients across Wales.
Join #TeamCRW today and help change the future for the cancer patients of tomorrow in Wales. Rest assured we will be with you every step of the way.
Shortly after registering you will be given a dedicated contact here at Cancer Research Wales who will support you through every step of this exciting journey.

- Bespoke fundraising pack

- Support from our #TeamCRW Facebook group
