Seven Marathons in Seven Days

What about Terry Fox, 143 marathons in 143 days. With only 1 leg (the other lost to cancer - metastatic osteosarcoma) and a tumor (which killed him shortly after he had to stop his 'Marathon of Hope'.

How about Rick Hansen who averaged 51km (~31miles)/day for 26 months in his wheelchair.

For our honeymoon, our flight from Philly to Miami was delayed and so we missed our connection to Santiago, Chile. We were not even going there to run the South American leg of a 7 day, 7 continent marathon. In travel experience, I don't know how you can just be on seven continents in seven days, let alone run a marathon on each one. I hope they have a private jet with beds to sleep in between the runs, because this sounds logistically impossible.

Given the monk example above and the super-marathons I have heard about, I am will to concede that people can run the distance, it's the travel that floors me.

That would certainly be an achievement but it rather pales into insignificance when compared with the marathon monks of Mount Hiei who start off running a marathon every day for a year and then ramp it up from there for seven years! They run on mountain paths in straw sandals, just to spice it up. Utterly astounding!
