I am taking my second shot at the marathon. My first one was four years ago, I ran 3:28 off about 25 MPW average. I have been running about the same amount per week since then. I would like break 3 hours this coming fall. I am starting to ramp up my mileage. How many miles a week should I get up to? I am 31, male, 6'1", 165lbs, with recent PR's of 31:06 for 5 miles and 1:27:30 for the half.
I was thinking 40-50 MPW would get me there.
Any thoughts would be greatly appreciated
