Marathon Pace?

I have a spring marathon coming up. My last 3 marathons have been around 3:48. I want to run at 3:45. I have always gone out at either 8:35 or faster and tried to hold pace or else gone slightly fast 8:25 to allow for fade. I was reading Alberto Salazar and he says go out at 8:40 and run the second half at 8:30. I'm afraid to try this because I think I'll fade anyway.<br><br>
I average only about 40 miles a week during training maybe hitting 50 miles on my longest week. I think that part of why I fade is low mileage, but I think I'm stuck with that mileage.<br><br>
Should I try Salazar's slower start?
