Every year, I watch the Tour de France. I would hear about climbs of 6%, 8%, etc. That means, of course, a slope of X feet per hundred. I thought that a climb of 6 feet in 100 was not so steep.
I was wrong.
The first hill I'm showing here climbs 180' in 3000'. That's 6%.
Here it is, the Scatchet Head road seen from Bailey Road (on Whidbey Island, WA):
I know that slopes are hard to show on a photo, but trust me on this: it's steep.
Happily, it's only 1 kilometer long. The TdF guys ride this slope for as much as 18km, and they finish at 9,000' elevation: very thin air!
I also tackle this climb, up Goss Lake road. Similar slope.
Why do I do this? I sometimes wonder.
The Tour de Whidbey is September 24. These two hills part of 50-mile southern loop I hope to ride. There are about four hills like this on that part of the tour.
I've ridden the entire loop piecemeal, saving the full 50 miles as a target "on the day"
I just thought you might like to know.
