Want marathon shape

I didn't get my other run in but, it is what it is.  I did 20.41 mile in 5h10m and burned 2895 calories.  I got some good sleep during the weekend, a 10 hour and a 12 hour sleep, must have needed it.  My problem is that I am still sore.  I went back and took a look at my training log.  Looking at the log always tells the truth.  From the beginning of February my long run was 7.02 miles and all my daily run were 3+ miles.  I then start my marathon training thinking I had a base, which I don't,  long run of 7 miles in 10 weeks.  I then ran down Salina Canyon on 4/6 for 13.26 miles.  Two weeks later we do a 16.07 mile run down the canyon.  No wonder I am sore.  I know better than this.  I am wondering if the marathon on 6/11 is doable for me.  I always preach to everyone out there that you should slowly build up your mileage over at least a 16 to 18 week period.  Staying on a schedule for the long runs.  I want marathon shape.  Not the 6 hour marathons I have been doing.  I can live with 4 to 5 hour marathons.  Need to take a look at what will get me where I want to be
