Thanks for all the input everyone, I really do appreciate it.
To give more detail, I am actually doing a 1/2 marathon in early september, which will be my final comfirmation as to whether I can do the full or not.
The training plan I am following is out of a running book by the guy who founded the running room. I don't have it with me but it actually doesn't peak higher than about 40-50km/week, with just a steady increase in the LSD run once a week.
I just like the challenge of the marathon. Placing well is a whole other story, but just finishing is just motivation to go out and run each day.
bikingbruise I like your story :P
And yes, my 16week plan starts last Sunday, although I have been trying to increase my running each month this year so far. I just hope I can keep up with it!
I did my first marathon in April and finished in 4:14. I started my training in October and had two injuries that took me out of training for a couple of weeks. My longest run was 20 miles and I really wish I would have done a 22 miler. The last 6.2 miles really kicked my butt and I think it had a lot to do with the jump in mileage. The 1/2 mary is a good idea but just know that there is a HUGE difference in the two and good performance in the 1/2 does not always equal a good performance in the full. IMO just wanting to finish is the best goal you can have for your first one but like everyone said, you have to respect the distance and if you're not ready by October than just find one a little later. Good luck!
