Very belated report, but I did indeed do it. The bus system to the start works well and I found the course reasonably straightforward. There are a few stupid issues - if you are doing the 10k and you are fast you will catch up everyone running slower than about 4 hr pace, meaning some very fast guys need to thread their way through hundreds of marathon plodders - not really a problem for the marathon runners but probably very annoying if you are an elite 10k runner.
Minimal support except for the last half mile, which is quite a tough uphill finish which I really enjoyed - nice finish to a generally fairly flat race. Same medal given to half marathoners which seemed a bit odd.
Next race in Turkey will be the Cappadoccia 110k in October.
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.
