Just FYI Paula Radcliffe weighs 54 kg the cyclist Leonardo Piepoli who is a man and the same height as Radcliffe weighs 52 kg. I do think that cyclists are on average heavier than marathon runners, but the top climber cyclists are not. The advantage Cancellara has on flat terrain is much smaller than the advantage a climber has in the mountains. In my personal experience with cycling and running I'd say that carrying 1kg of fat running is a smaller disadvantage than carrying 1kg of fat cycling in mountain terrain. This is reversed when you consider cycling on flat terrain.
