You should go exploring, especially if you’re travelling down from oop north to visit. I reckon the options are:
1. Stick to the named trails – you wont get lost and they’re good fun but you’ll miss loads of cool stuff.
2. Explore – The primary biking area is bounded by 4 roads so as above, cycle til yer legs drop off – eventually you’ll hit a road and use an iphone/map/compass/local/astronav to figure out which road it is and turn round and head back to base.
3. See if a local can help show you around the best bits.
For something more organised check out the Fountain Inn website as it contents quite a good map of the area and some of the downhill trails (which are quite good fun and no too scary) – even for an southern pansy like me.
Some of the best trails seem to be a local secret – a bit like the cola recipe and the Colonel’s secret mix of spices…
Let us know how you get on anyway!
EDIT: If there is a MiniDH race then the downhill runs are probably best avoided – although I can’t imagine they’ll all be in use.
