I think I need to make clear that my objection is to the claim that this is "the best 10K in Britain". From that claim one makes assumptions. I've attended a number of race events which don't make such claims, and yet go buttery smooth and have additional touches which make the event stand out.
I've attended various events, and it's rare for everything to go well, so I don't have huge expectations. But I was impressed by the amount of things that didn't go well with this event. Adding together all the little (and big) grumbles that I heard and have read people make - together with my own observations - I do find it objectionable that the organisers are still promoting this event as one of the best in the UK.
I enjoyed the day. I had a good time. But I am aware it could have gone better, and some opportunities were missed. Music at the start of an event creates a positive atmosphere. Coming round a bend into a water station, it is ALWAYS better to have the water station on the outside bend so people can see it more clearly, and can see which tables are clearer. Don't narrow the width of the running track to half after only 500 metres, especially if you haven't made sure that people are set in their correct time bands, as that will lead to frustrating congestion. Close the entire road for the hour or so that it needs, or find another course. Arrange that everyone gets their t-shirt at an appropriate time and place. Send out everyone's racepack to the correct address (a number went missing - including mine). Arrange funnels so that people can speedily get their goodie bag and move away.
Don't make claims that you can't live up to.
I've heard that the problems have been caused by the organisers increasing the number of entrants, and that the event was better when it was smaller. So be it. Either limit the number of entrants to a managable level or stop calling yourself the best 10K in Britain.
