I did that, twice. Walked up a good bit of Townes Pass though, both times. I think the hardest route I've ever done climbing-wise was the Appalachian Double Cross 1000k. None of the climbs were as long as the ones on the 508, but they are relentless. And since it was an unsupported ride, my bike was a good 15+ lbs heavier. I barely made it in the 75 her time limit both times.
The good part is that it's easy to prevent saddle sores when you spend so much time out of the saddle!

but coming back down got sketchy, even w/front brake.
