Yeh WORCA are amazing, I was in Canada for 3 months on a student exchange and I went in the British Columbia High School XC MTB'ing Provincial Championships which was on a trail made by WORCA, also the day was effectively run by WORCA. The trail was amazing with an awsome variation in terrain ranging from technical root sections to fireroad climbs and descents, and some smalle bridges. Hats off to WORCA they are an amazing organisation
