Personally I didn't have a problem with getting water (I carry my own bottle) but two friends of mine who were also running experienced difficulties later on. I finished in 1:51 and I noticed that the later stations were running low when I passed. My friends came in at 2:20 not at all happy with the fact that they could not get a drink from 9 miles onwards. Considering the nature of the course and the weather this is inexcusable - especially as the PA announcer was stressing the need to take on plenty of water before the start. Surely the organisers knew how many entries they had, and should therefore have made sure water supplies were adequate. It wasn't as if they were splashing out on expensive bottled water, opting instead for dustbins filled with ordinary water, leaves, insects and other miscellaneous debris. Therein lies the reason behind my ALWAYS carrying my own water supply.
The organisers of this race need to give this matter serious consideration before next year. I saw requiring medical assistance a few people requiring medical attention, I can't help wondering how significant lack of water was in their getting into trouble.
