I don't know what gearing I would need to climb 15 miles @13% but I don't think I have it in my legs. Sounds ridiculously hard, as does 10K feet in 30 miles. I've done centuries with 10 and even 12K feet, but 30 miles?
Some people do a thing called "Everesting" where they climb 29000 feet in one ride. BF member Vireo did it once in under 90 miles, I think, and it was about 12 hours. He did one recently in about 125 miles and it took 16 hours.
