I'm glad I skipped NYC in 2012. I wanted to do that, but the cost was just too much to justify so I went and entered Chicago instead and then went to NYC in tourist mode. In hindsight that was a very lucky decision!
Tim - My London marathon was a tough one as well. I did it two weeks after running Paris a couple of years ago and my legs rebelled in the later stages. I was ok until about 18 miles and then all power to the engine went bye-bye!
I need the 5 x 20 to be in good condition for a marathon. I didn't do that for LN and suffered badly as a result.
TinkerBEL - I've got two more sleeps before I'm off on my travels too! Although mine is more swanning about in tourist mode than important family stuff. Hope you have a great time seeing your folks.
orapidrun - I was lucky as I entered the last year before it became a ballot (2012), so I got in on a first come first served basis. It's certainly a popular event and much like most other big city marathons one that's becoming more popular year by year.
I'd imagine the odds might be slightly better than they are for London, but I'm not sure how the ballot separates out allocation of places to foreigners. From a UK perspective it's not a race that seems to attract much interest at all, not sure if that is also how it plays out from other nations.
