Is there much XC type riding at Whistler, or is it mostly geared for downhill and freeride (neither of which my bike will handle.) I just don't want to waste a trip if there's not much XC type stuff. Thanks!
Whistler has plenty of xc options such as Comfortably Numb, Riverside, Flank Trail, Trash, Lost Lake, Emerald Forest, Rebob. Find a bike shop once you get to town and let them know what kind of trail you're looking for. I'd offer to show you around, but...well...I'm not really into climbing.
As for Pemberton, their trail organization is PORCA, but I don't know if they have a web site.
