Having watched the highlights last night your critcism isn't accurate, there was some coverage/interviews with the field other than top 3.
Having ran in the middle of the pack, chatting with others what I enjoyed was watching the front runners as this offered something very different to my experience of the race. Much rather see the elite racing rather than more coverage of the same sort of runners I spent 4 hours with and train with day in day out.
Not sure what you mean by the last sentence re. not being Welsh etc. S4C is a Welsh language channel, thus not sure what you were expecting? If watching Paris marathon on Canal+ would you whinge about too much coverage of French runners?
I think you've left yourself down with that comment, completely not in the spirit of running or Eryri event. Suggest you follow soccer where you will feel more at home with that sort of jingoistic nonsense.
