Fancy doing something unforgettable in 2026? Take on the Big Three.
Each year, just 12 people take on this incredible challenge – climbing the three highest peaks in England, Scotland, and Wales within 24 hours. Could 2026 be your year?
If you’re ready for a serious adventure, want to push yourself physically and mentally, and raise vital funds for Martin House along the way, this could be the challenge for you.
You’ll need stamina, determination, and a good pair of boots – but you won’t be doing it alone. You’ll be guided by a small team of mountain leaders from Overlimits, our outdoor adventure experts, so you’ll be in good company.
What’s involved?
- Three Peaks: Ben Nevis, Scafell Pike, and Snowdon
- Distance & Ascent: Around 24 miles on foot, with over 3,000 metres of climbing
- Route: Starting and finishing in Boston Spa, all transport and routes are arranged. You’ll begin with Ben Nevis, move on to Scafell Pike, and finish with Snowdon.
- Time: 24 hours to complete the full challenge (the clock starts from your descent on Ben Nevis)
- Support: Expert mountain guides, event transport, and a guided training day to help you prepare
- Experience: Stunning views, unforgettable memories, and a true test of endurance
This exclusive event is for Martin House supporters only, with just 12 places available.
