I'm not quite as old as you lol im 45 now but did my first Marathon at 44 in Edinburgh in may 2012 I had only started running in summer 2011 but really only put the miles in after December. Purely as a guide for you I did a 10k in 51mins a half in 1.49 so set myself a target of 4hours and set my training round this. I don't know you so can't comment on how hard you will train I made the mistake of thinking I had done enough but in hindsight I should have done another 1 or 2 LSR.
Also it happened to be a roasting hot day. I broke the race in to four parts and set my self a time for them. At the half way stage I was 1min ahead and felt great at the 20m stage I was 1min behind and still felt great more in mind than body lol. But by the time I got to 23 miles I knew I wasn't going to beat 4 hours and didn't feel like I hit the wall or anything just got really slow, so thought sod the time lets finish this without stopping and I can assure you I was over the moon with my 4,12 inside but told my wife and daughter I was coming back next year to crack 4 hours.
So I think you should go for a target that is realistic and makes you train hard for it but if you don't reach it on the day don't beat yourself up.
Good luck and stick in
