I actually got to ski peruvian one day with the whole under the lift section groomed. I've always theorized that a 100k vert day could be accomplished by taking 42 peruvians in one day doing 2 minute T2Bs. While a 2 min T2B was achieved, I just don't think it's possible because of lift stoppage, getting in line, all that jazz. Someday I'll try it though
