I'm 31 and running my first marathon this year - London.
I have been running 5-7 miles 2-3 times a week for about 18 months now - times between 37 - 54 minutes.
I am starting my marathon training, but I don't have a plan, clearly this is a little late! I also have criteria where I don't want to run at weekends. So have a realistic maximum of 4 runs a week. Am I being foolish, or is there a plan out there that will suit me. Ideally I want to be running as close to 4 hours as possible (am I kidding myself?).
