For what it's worth I was one of the people limping along with an injury. I ran the first 3 miles and then cramp kicked it and reduced me to walking pace. So I got cold very quick. My main complaint is that none of the marshall stations could help at all, not even point me in the right direction to jack it in and get warm. I was freezing and had no choice but to just jog on. I got to mile 15 (twice round that stupid peninsular as by that time I was disorientated and shivering pretty bad). Eventually I knocked on a random house door as it was getting stupid and the very kind owner gave me a lift back to the car park.
So for me I think that's an inexcusable position to put runners in, and ok perhaps part my fault for not wearing warmer clothes but they have a duty of care to the people who entered and I was anticipating running a decent pace so I hadnt packed a survival bag!
Point 2 - my wifes first marathon. Greeted over the line by... nobody.
Point 3 - my brother finished top 3 and got.... nothing.
I would be ashamed if I was the race organiser but such is life, worse things happen at sea, I'll not race it or recommend it again.
