Get to the top of all 15 Welsh mountains over 3000ft, self-propelled and without transport, inside 24 hours. The route runs from the summit of Yr Wyddfa (Snowdon) to the summit of Foel Fras.
We can also run it in reverse, but that needs booking with us directly — it puts the technical Snowdon section in the dark and at the point you're most tired.
Depending on the route taken, it's around 40km from first summit to fifteenth, and closer to 50km once the combined elevation is factored in.
Is it for you?
You'll need a good level of fitness and to be used to long days in the hills. A bit of experience on grade 1 scrambles and steep ground is helpful.
Prefer to take your time? The same challenge can be done at a more leisurely pace over three days, with the option of wild camping along the way or staying at our accommodation in Anglesey.
What we offer
Our qualified mountain leaders know every one of these routes first hand and are there to guide you, giving you the best possible chance of completing the challenge.
We meet just off the A55 near Aber Falls (the end point) and transport everyone round to the start at Pen y Pass. We also have a support vehicle in each valley for refuelling and changing layers.
