A Fun Fundraiser
Proceeds from the Back Forty go towards new trail construction in Whistler and mountain bike programming for the Líl’wat Ka-xléq-a (Líl’wat Rolling) Indigenous Youth Mountain Bike Program.
The Back Forty was inspired by the legendary NIMBY 50 and brings the spirit of that event to Whistler, in a totally different package. The three stage course stretches from Cheakamus, then up the Westside and into Alpine.
