Welsh 3000 Challenge (14 Peaks)

Next event 18-19th July 2026

Welsh 3000 Challenge, 14 Peaks – The best mountain running / walking challenge in the UK.

The Welsh 3000 Challenge (14 Peaks) climbs all the 3000ft peaks in Snowdonia in a continuous journey. Highlights along the way include summiting Snowdon, the highest mountain in Wales and England. The knife edged ridge traverse of Crib Goch*, scrambling over the incredible Glyders and Tryfan before taking on the stunning and remote Carneddau range.

Our next open events are on:

  • Saturday 18 July 2026 (20hr challenge) £299
  • Saturday 18 July 2026 – Sunday 19 July 2026 (2 day challenge) £399
  • Paddy Buckley Round 21-23 July 2025 (3 days) £749
  • Other dates available for groups, please ask.
  • For booking enquiries, please contact info@climbsouthwest.com

We have been guiding the Welsh 3000 challenge regularly for over 20 years, with a range of client groups from large charity events over three days, through to groups of fit runners, aiming to complete all peaks within 12 hours. The record, (from 1st to last peak) stands at an almost unbelievable time of 4hrs 10 minutes. This doesn’t however, include the time taken to climb the first peak nor descend the last. Most people will aim to complete this challenge over 2-3 days. We offer the Welsh 3000s as a 20hr guided challenge or spread over 2/3 days.

About the event

Welsh 3000 Challenge (14 Peaks) Event Profile

What's Involved

Total distance is about 50km with a height gain close to 4000m, the Welsh 3000s completed inside 24hrs is brutally tough, but a fantastic challenge. To complete the challenge over 2 days is still very difficult. Not one to be underestimated but achievable by anyone with a good level of fitness. There are however, some sections of exposed scrambling. The most famous being Crib Goch. Previous hill walking experience would be highly recommended.

You’ll climb all 14 peaks officially recognised as being over 3000ft but we may also include some others that fall directly alongside our intended route. You are welcome to join us as an individual, part of a group, or representing a charity of your choice.

What's Included

  • Low ratio guiding (typically 1:4) and supervision by our highly experienced and qualified leaders. 
  • Refuelling opportunities and support along the way. Food and drinks in 3 key locations.

Safety

Safety is our number one consideration, so we work on a very low staff to participant ratio. We only use qualified Mountain Leaders and Mountaineering Instructors for this event. All have extensive experience in Snowdonia and know the route well. Our run leaders are also experienced Ultramarathon runners.

*The Crib Goch ridge will only be undertaken in good weather. This section can also be avoided by anyone who wishes to do so. One of our team can lead you around and you’ll be able to meet your group at the other end.

**Carnedd Gwenllian sits on the ridge between Foel Grach and Foel-fras. With just an additional 30m of climbing required to reach the summit, it is usually overlooked as a qualifying peak (the 15th Welsh 3000ft peak). We will pass over the summit on our route, completing a total of 15 named summits over 3000ft high.
