What’s Involved

  1. Traditional Route
    • Slowly walk up to the top of Snowdon. This can be done very early in the morning (ideally in the dark), or on the evening before the challenge. There is an area for camping or bivvying that is normally fairly sheltered near the summit.
    • Start the walk as soon as it gets light (the walk begins on Snowdon's summit).
    • Walk the first three peaks down to the road above Nant Peris where you can drop off some kit and take on food and drink.
    • Walk the five/six peaks of the Glyder section to Llyn Ogwen where you can take on more food and drink.
    • Walk the remaining seven peaks of the Carnedd section to the finish point, Foel Fras (the final summit).
    • Drop back down to your pickup point at Bwlch y Ddeufaen, or above Abergwyngregyn.
    • Celebrate!
  2. Crib Goch as the Initial Peak
    • For those not camping on Snowdon, there is a popular alternative route for the first section. This is the fastest route for those not making the ascent to Snowdon the previous evening. However, it cannot be used for attempts to break the record. It is also unsuitable if you wish to climb the first peak in the dark, unless you know the area very well.
  3. North to South
    • Another alternative is to complete the route in reverse ie. North to South (again, this cannot be used for record attempts). However, this website focuses on the South to North routes.


Although a support team/individual is not strictly necessary, it is extremely helpful.

You will need:

In the ideal world a support team would drop you off at the start point; arrive at Nant Peris for about six o’ clock in the morning to cook some bacon barms over a portable grill; drive to Ogwen a few hours later with some hot soup; and be standing applauding at the end-point when you finish in the evening. It’s a lot to ask, so you may have to compromise on some of these points!
