Belgian completed a marathon per day for 365 days (average time was 4 hours)

It's impressive no doubt. I think I'm getting immune to these feats of amazing endurance.

There are plenty of people who do that sort of mileage.

No, there aren't.

Is 180+ miles per week, with no doubles, at an average of 9mins/mile with some sub 7min/mile impressive?

I sure think so.

BFD...These types of 'characters' have been around for decades. They couldn't cut it with 'quality'..ie a 214 marathon; so in a screaming attempt to say "HEY, LOOK AT ME"; they do these kinds of stunts.
