I have several hill challenged friends who will be turning around at Taylor. There will even be a lightly staffed/supplied rest station at Taylor.
More importantly I think it is highly likely the Patron of the Pelton will control this to be a very congenial social ride where noone is left behind. It may split into an A group and BC group but I'm sure if you elect to ride the 55 you will not be left in the wind all alone.
