Marshalling the Moyleman

[The Beast of Bevendean]

I thought a thread on marshalling might be indicated.
We learnt from the first running that:

• We need many more
  
• We need more particularly in the Castle Hill/YBR area
  
• It is reassuring for runners to see a marshal even if the way is obvious
  
• On Sundays driving from marshalling point to marshalling point is not to be relied on
  

We were lucky, of course. Marshalling in poor conditions on the Downs in March could be much more challenging.
Brighton marathon divides the course into zones, with zone managers for each. Is that too elaborate for us, or useful?
We only had one injured runner to cope with. How would we have managed with multiple and more serious injuries?
Are there any lessons we can learn from the Sheffield half affair, apart from the obvious, that if you want to communicate with runners, do so so they can hear you, and plan your water supply well in advance?
