Nog, Gotta agree withe guys about the Whytes/Cwm Carn climbs - some of the best man made climbs around. Few things about the routes: The wall is techy on the graveyard section - there's one part on that section yet to clean yet! The Penrydd'sa bit of a climb after the initial interest near the centre.
The Skyline has a great short cut - at the end of the Granada section, it goes left. If you go right and drop down what is really a drainage gulley and at the end go right again, you rejoin the Skyline proper and get to do the best bits. In my opinion! I think it was called the July route, when they where only part way through the Skyline. The only techy part of note on the Skyline is the rock steps on "Jetlag". Saying that, Jetlag is a great way to finish the Skyline! For some, if you've never done any of the South Wales trails, the anti motocross gates are a pain. Alternatively, it's a good chance to regroup on the climbs and the decents. With the ideal excuse to break out some munches! |
