mel - the temperature was 'normal' but I heard from a native that it was warming up a lot quicker this year than previous years. Apparently the marathon isnt well known there. I heard so many things about the marathon before I went and was really excited.
I'd recommend emailing the RD with your feedback as they are thinking of moving the walkathlon/half marathon to a later point in time. I think this would help you as a speedier runner. I'm really hoping that they improve the marathon for other years and runners - then at least I could understand and accept my bad experience.
By the way - the girl that got lost: This is her comment from the marathon page:
"Ok well that was an experience! my first dnf in a marathon and my first overseas one! that wasn't planned! Not the day that I had expected, and not necessarily one I would want to repeat in a hurry! Single female, strange country, no marshalls where expected so got lost on course, locals who didnt know how to help, no water so having to 'recycle' other bottles. No contact number for incase of emergency at race headquarters and had to ring friend to rescue me as I hsd no idea where the hell I was! On that note thank to Peter who came to my rescue. There is a lot more I have to say on this but will post in a private email. If I come back next year I need assurrance there will have been changes for the better because someone could have got hurt, or worse, yesterday!
