Welsh 3000 Challenge (14 Peaks)

The event is a guided mountain traverse that visits all officially recognised Welsh 3000ft peaks in Snowdonia in a continuous route. The itinerary includes summiting Snowdon, traversing the knife edged ridge of Crib Goch, scrambling on the Glyders and Tryfan, and crossing the Carneddau range. The route may also include adjacent named peaks that lie directly alongside the intended line.

The total distance is about 50 km with close to 4 000 m of ascent. Some sections involve exposed scrambling, and previous hill walking experience is recommended. Crib Goch is only attempted in good weather and can be bypassed by alternative routing if requested.

The event is offered as a guided 20 hour challenge or spread over two or three days. Groups and individuals may take part, including charity groups. Typical guiding ratios are low, around 1:4, and the leadership team comprises qualified Mountain Leaders and Mountaineering Instructors, with run leaders who have ultramarathon experience.

Participants receive refuelling opportunities at three key locations, support from a following team, and transport back to the start. Organisers have run guided versions of this challenge for over 20 years. Some groups aim to complete all peaks within 12 hours and a fastest recorded time for the line is cited as 4 hours 10 minutes with specific caveats about timing.
