Steve Freides said:My son and I rode the Skyline Drive today, haven't done it in a while,
it's no easier than I remember. About a mile and a half to the top as
we rode it from the eastern (Route 287) side. It sits at the border
between Oakland, in Bergen County, and I'm not quite sure what in
Passaic County (maybe Ringwood?) in New Jersey not far from the NY State
border.
Anyone have any statistics on what percent grade this averages?
My son also asked me how it would be categorized in the TdF - I thought
that might be interesting to know, too. We both guess it would be
categorized but just, probably Cat 4. My guesstimate is 8% average
grade with sections of 10-12%.
BTW, the answer to the second part of your question is complicated.
The rating system they use for climbs in the TdF is not
straightforward. They use elevation gain, grade, sometimes road
surface, what hills have come before it in the stage, and more voodoo
it seems. The classification is knocked down if there are flat parts
or, worse, intermediate descents along the way. They really give the
highest ratings to very long, consistent climbs.
Since you are talking of a stretch of road about 2 km long or so, at 6%
grade that would be 120m of elevation gain, at 8% 160m. That is at
best a Cat 4 in comparison with the climbs they do in the TdF.
The HC climbs for the generally quite long. For example, Col
d'Aubisque on stage 16 this year was rated HC; it is almost 17km and
climbs almost 1200m in that distance, a tad over 7% average. The stage
before, 15, had an HC climb ... up to Pla-d'Atet. That was a shorty,
just a bit over 10km over which they climbed about 860m. If one were
climbing that alone, or just riding up the valley through Arreau to
Vignec then up to Pla-d'Atet it would likely be a Cat 2, but since it
came on the heels of 4 preceeding Cat 1 climbs they probably bumped it
up a little.
