Established Marathon or first running

Van.Bosch

Hi, just wanted to get your opinion on this. I am planning on doing a marathon next May, I had been looking at Limerick/Belfast which are both established although I have heard negative reports re pacers at Belfast on here. I know I have 5.5 months but I had hoped to have a few more decent mileage weeks done before I start the 18 week plan. I'm only getting back into regular running after a few months lower mileage. So I had wanted to get the mileage up to be starting from a good base.

Should I stick to the original plan or do another marathon a few weeks later. I was looking at the Rock n Roll Liverpool. My question is should I miss the 3 weeks pre training and do an established race or get the extra prep in and do a for profit race where the company are running it for the first time and have a bad reputation, although their Dublin half was ok?

Can't do Cork this year and want to complete it by then.
Thanks

Derry was very well run last year. Sign up early. They only opened last week and l think there are only a few hundred places left out of 1500.
