Who cares? It was all a scam, and if he was jogging 26 miles a day it wasn't running a marathon.
It was just jogging 26 miles a day. Others have done it, and not made a big hairy deal out of it.
So it's all a big fantasy scam.
His whole "420 [or however many] Marathons in a Year!" thing is to me and I imagine many other serious runners pretty laughable and bordering on offensive.
To me a "marathon" is a RACE, i.e. something that a lot of people are doing at once, complete with bibs, organization/sanctioning, some sort of official timing, the whole deal. Some noodle jogging ~ 26 in his local park is not a marathon.
