I’m not big on the camping bit but would definitely do parts of it. I want to go to Columbia and do the Letras climb nearer Medellin - 50 mile climb - combining these would be awesome!
I didn’t go with the group. Instead, there are one or two Gran Fondos on that climb each year, I did one of those. The good thing about those big events is that they close the road down for cars, so you only have to worry about pedaling.
