Dublin City Marathon

As the biggest marathon in the country, the DCM is the flagship for most Irish marathon runners, be they first timers or consistent long distance runners, so what do people look to achieve and what have you done to prepare? Who falls into the following groups and what are you expecting on the day.
Just complete it (first timers)?
Complete it to add to a tally of marathons (110 marathon club etc)?
For fun ??
For PRs?
As the numbers keep growing , I wouldnt be surprised to see 12K this year, there must be lots of different motivations and different things people are doing, so start off, this is after all a running discussion site
