Black Diamond Yr Wyddfa | Snowdon24 2027

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? Being UTMB-indexed, this is also a great qualifying or preparation race for UTMB Mont Blanc. The individual challenges include a 50k, 100k, and 100m mile UTMB-indexed challenge.

Snowdon 24 can also be entered as a pair or team (up to 5). Taking part in a relay format is a fantastic and unique way for people to come together for 24 hours as friends, colleagues, or teammates and work towards a shared goal, whether that's many ascents or just to keep going and raise money for charity. Every person in the team contributes, whether they make one ascent or ten.
