Akebono Vs. Tokyo Marathon

Akebono, the retired sumo superstar, plans to run the Tokyo Marathon on the 22nd of March. He's written on his blog that he's turning 40 this year, and that at 220kg running a 26mile marathon will "feel pretty tight". Apparently they stop giving finishing times after 7 hours, so he's aiming to finish before then. How hard can it be? He only needs to keep walking, right?

Still, good to see he's keeping active. His blog shows him training at home in Hawaii in a regimen that includes lots of food and some treadmilling. He might be approaching this challenge the wrong way.
