My only concern about Dublin is that when I booked online my excitement got the better of me and I registered in the 4-hour plus category (the only other category being less than 4-hours). I was in the sub-4 hour category last year and still got hemmed in by walkers after half a mile.
I e-mailed the race organisers to explain my predicament only to be told there is nothing they can do as I have been allocated my number - they did suggest that I get towards the front - I assume of the over four hour group. I emailed back suggesting that I cancel my registration and re-register - there has been radio silence since. I have contemplated either registering again (€80 at this stage) or starting so far back that the path would be relatively clear when I crossed the starting line - not really a runner as I'd prefer to be with runners nearer my own pace. I guess I'll play it by ear on race day and produce my booking confirmation e-mail (showing my number) and the results of the Cork Marathon (my name isn't that common) and persuade the stewards to let me in the sub-4 hour pen (either that or hop the barrier).
Other than that I don't care what the day throws at me - I'm ready.
