Pinch punctures would be the main cause of flats his weekend….
options are
wuss group out for a scenic jolly in the hills
general trail riding group, mainly for the rad mincers out there, similar loop as the wuss group with an extra descent/looong climb and a slightly more continuos pace.
Then there’s the ‘b’tids are gonna kill me group’ after a short warm up you get thrown down a steepish rooty off camber natural DH trail(carved by the dh’ers), then climb out and possibly hit another DH before ducking into great wood to do revenge of the stump and the chimney then a race out and along the ridge to meet up with the others for lunch and rearrangement of groups, then some combe bashing titting about sessioning bits and taking the piss, this group will go further, will do more climbing(and descending) and will more than likely detroy the guide, before the end at which point everyone should be also close to death….
