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.

2026 Course Overview

We currently expect the 2026 course to be the same as 2025:

• 3 stages (climbs and descents timed, combined fastest total time wins)

• 2 untimed transfers, plus a quick pedal to Apres

• 1 timed descent (in Stage 1) presented by OneUp Components

Get out there to familiarize yourself with the three stages!

Total Timed Course: 28km / 1,461m climb / 1,471m descent

Stage 1: Checking Out Cheakamus

11.2km / 486m climb / 496m descent

Stage 2: The West Side Wallop

8.0km / 505m climb / 352m descent

Stage 3: Alpine Epic

7.1km / 402m climb / 561m descent
