Funnily OakLeaf, I am right with you there because that is probably about as far as I've made it! It really is quite horrid. But a ride up there every week or two and my legs are the toughest they've ever been. I'm still slow as a slug though!
It is actually a 14.3mile climb at 213feet/mile and if you do it in the down direction you still get 142feet/mile of climbing! It is pretty horrid in either direction and has 18% climbs in both directions.
I have done the whole thing in the down direction and survived (I got deposited at the top and left my car at the bottom). But I have never managed the whole way up because I just don't think I could face all the climbing involved in coming down again!
The ride I quoted is going "up" as far as a certain sidetrack and then turning around and coming back "down" again and it works out at 177feet/mile over both directions. As you can understand, I use the terms "up" and "down" quite loosely!
PS: Now I've actually worked out how damned steep it is I never want to go there again. I am a wimp at heart!
