Looks good - I may do it as a post birthday run Terry, being on the 100MC site isn't a requirement for inclusion in their count. There are quite a few runs which aren't, either because they don't ask or don't want to be...
Transfers are allowed, and deferrals may free a few places up - I would expect April to be the best bet as people often drop if a spring marathon didn't go according to plan. The Facebook page will be the best way of grabbing one as quite a few people have asked so they won't hang around long.
Its a good event - easy to get there using the huge numbers of buses they supply at Taksim Square, which has excellent connections. There is another bus pick up point too - its not worth trying to get to the start independently. Although lots of good hotels around Taksim so that would be a good spot for a stay anyway. Not a great deal of crowd support, but that doesn't bother me - plenty of water, services, etc. Pretty flat apart from the last half a mile but I really liked having to work hard at that point, esp as thats where most of the support was.
I got in too, so pleased about that and have booked hotel a few miles away hoping wife can drop me near the start. I can't see the start time on the website but the countdown clock suggests it's 10.30, which seems late ?
