Welsh 3000s

On 17/18 June 1978 John Wagstaff of West Bromwich Mountaineering Club completed a triple crossing[clarification needed] in 22 hours 49 minutes, a feat which has yet to be repeated.

[2][3] The walk is also known as "The 14 Peaks": Carnedd Gwenllian (or "Garnedd Uchaf") is not always included, as it has the least relative height, being little more than a bump on the ridge rather than a separate summit in its own right.

There is also an option to include a sixteenth top, Castell y Gwynt in the Glyder range, which has been reclassified as a Nuttall since a survey in 2007.

While challengers can choose any route and summit the mountains in any order, anyone seeking to beat the record must start on Snowdon.

Many walkers and runners prefer the alternative route, starting with Crib Goch, then visiting Garnedd Ugain before summiting Snowdon.
