sub 40 or 45 min program?

I'd be interested to see your modified program for the marathon, but I'm not sure if I'll be able to use it this year. The problem is that I don't have much time before the marathon which is on October 10th. That only leaves about 10 weeks before the race, so I was planning to take a few days off and then do an off training / build up period for the first couple weeks, then go through an 8 week accelerated marathon training program. The program I found basically increases mileage for 6 weeks and adds some strides, strength training and recovery runs, then it tapers off for the last 2 weeks.

One question I have is whether I should do one or two longer runs during my 2 week "build up" period, or should I stick to easy runs of up to 1 hour?
