I have been running for the past 18 months or so and did 3 half marathons and a few 10k runs last year. I've got it in my head I really want to do a marathon but with the time of the year there are some at the end of May and then that's it until September/October time.
I currently run 3/4 times a week and my last long run I did was on Sunday which was 11 miles.
There is the Liverpool Rock n Roll marathon which I would love to do but it's the end of May so only 5 weeks away, have I left it too late to train properly for this? There is also a half marathon the same day which I planned on doing but I really want to do the marathon distance.
What do people with experience advise? Should I wait until September/October time and do a proper 12 week training plan or could I go for the end of May?
