I finished my first marathon with a 3:50 finish time using Hal Higdon's Novice training program. I am thinking about doing another marathon next year and was hoping to shoot for the 3:30 finish time.

I have heard alot of people out there recommend Pfitzinger's different programs. For those of you who are experienced marathoners...does anyone recommend his programs?? If not, what other training programs would you recommend you reach that goal?? Thanks for any comments posted....much appreciated.
