What are you talking about? If the winner drawn is not there, then a re-draw will take place until a winner is present. So if a lot of 'winners' had left, then logically more redraws would be required. That was not the case last night.
Who knows? You never announced your bib no but I doubt it. I think only one or two 10K women was drawn. Only 1 man 10K was drawn before a winner was found.
Here is my blog post for the Pocari Sweat Run Singapore.
Honestly my experience was not bad like some others have said and the bottlenecks did not affect me that much because I had started in the first wave. There was the occasional pedestrian who had threatened to block my path, but still I didn't have to really do a lot of weaving like some runners starting in the later waves may have had to.
Anyway enjoy the read.
