Not giving up and going home when you get to the top of the first climb and feel like utter cack, local trails you forgot existed and of course; long, dry, dusty, wooded downhill singletrack without another soul on it. 
An honourable mention too to Bristol Trails Group and a heads up that the cheeky trail known to some round here as "Happy Campers" now has a fence at the bottom of it to stop the cows getting out.
