Thanks for that.
The one and only time I`ve had to do scrambling was on the race up and down Snowdon.
My usual runs are in the Yorkshire Dales, The Cumbrian Fells and forest races of varying gradients dependant on where they are - Delamere will be quite flat, where as ones in the Lakes can have a lot of gradient.
The majority of my runs are on footpaths in these areas, which can be quite technical, especially in the Dales, but nowhere near Striding Edge or Crib Goch ( which I`ve walked many times )
The introductory race in Snowdon sounds pretty much like a hard trail race / fell race by it`s description and is bolted onto part of the course of a Sky Running Ultra on the same day.
From what you say about sky running, it sounds a bit out of my league tbh and sounds very much like extreme fell running and having done a couple of fell races, I can safely say that they`re a different breed - vests and shorts in January on top of moor !!!!!
Have you ever done any off road stuff in the North ?
The reason I ask, is that over the years, I`ve developed a lovely little network of country pubs and cottages to stay in, that are out of the way and really cheap to stay in, ranging from £55 - £70 a night room only. Pubs that are well off the tourist track and as a result lots cheaper, but much nicer due them being privately owned and much friendlier.
If you ever need anywhere to stay prior to a race in N Wales, anywhere in N Yorks or the Lakes give me a shout
