Perhaps an interesting comparison is the Tour de France, where cyclists cover approximately 21 centuries in a month. Marthoners can't run 21 marathons in a month. One reason might be that you don't have that pounding of your joints on a bike, but another might be that it's easier to do a century on a bike than run a marathon.
