Yes, but didn't two Aussies just finish running a marathon a day for the last year?
To me, the whole thing hinges on "running" a marathon vs "completing" a marathon, and "riding" a century vs "racing" a century. I could walk a Marathon in 6 hours, and it would represent very little appreciable wear and tear (and as a seasoned hiker, I know I maintain 4.5 mph on asphalt). I have gone on a 80 mile bike ride that damn near killed me.
So I will stay with "it depends".
