The Climachx is what you’d expect. Man made trail in a forest, some nice sections before the final (climax) descent which is cracking.
The Mach 1, 2 and 3 are more old school riding. Bridlways, doubletracks and bit of singletrack out in the hills. Nothing actually built for mountain bikes but if you enjoy a ‘proper’ ride, with lots of climbing, big views and a few interesting descents then you might enjoy them. Don’t expect a trail centre and DO take a map, don’t rely on signposting or the official trail map.
