From September 3rd to September 5th 2010 it's the second Old World Mountain Bike Championships (OWMTBC for short), and it's just up the road in Betwys-y-Coed, North Wales.
Sponsored by Retrobike and Howies, it's a weekend of old bike related activities in the company of like minded people (with lashings of beer on the side). It might be sometime before it hits these shores again, so best get 'in' while you can.
Here's the Aftermath thread from last year to give you a flavour of the 2009 event http://www.retrobike.co.uk/forum/viewto ... ght=owmtbc
