I don't know about a 2009 inline marathon but in 2005 I was there for it. Back then it was a 2 loop course so you got to see everything if the did the half and got to see it twice if you did the full.
I can't remember if 05 or 06 was the last one but it was discontinued. If the link is correct it looks like they are bringing it back. I checked Disneyrunning.com and don't see anything but it might not be there since it isn't really running.
I would imagine it would have had a booth at the expo so maybe some WISHers who were there could fill us in.
