This will give you the following sub-detail for the selected segment in the “Metrics” window top right of the page: (a) distance, (b) elevation gained and lost, (c) max grade, (d) average grade (e) that segment's climb category – e.g. Cat 1, HC, etc., and (f) FIETS score for the segment.
The #3 ranked climb in Canada, we begin our ascent at the northern end of Lillooet Lake, just north of Whistler, BC. After a very brief and gradual start, we pitch up to double digits and stay in the 8-12% range for the next several kilometers - it’s not #3 in Canada for nothing. After a brief start, for the next 2.6 km/1.6 miles we average a quad screaming 10.3%.
The views along this climb are of rugged snowcovered/snowcapped mountains (depending upon the time of year) up and down the canyon we climb through. The Canadian mountains from Vancouver up to and past Duffy Mountain are extremely steep and nearly always fully covered by heavy forest and foliage. These mountains are habitually deep green, a testament to the climate and abundance of water in this Canadian province – 60% of BC is forested and 95% above 1,000 meters/3,300. The significant challenge of this climb coupled with its setting in and views of the rugged Canadian Coast Mountains makes this a must-do climb for those cyclist in the area or traveling to or through it.
The most populated area near Duffy Mountain Road climb is Whistler and the out-and-back from Whistler to the top of the climb totals 124 km/77 miles and 2,130 m/7,000' (Map). The two Run Away Truck Ramps along the southern (descent side) of the road attest to its steep grade.
Roadway surface and traffic: The roadway is excellent, although there is not much of a shoulder for cyclists to ride in. However, there is minimal traffic in the early morning and moderate later in the morning and afternoon. This is a highway climb and for those with a major or acute aversion to traffic, it should probably be avoided.
