If you're a 2:45-2:50 marathoner doing 60-70 miles a week a you were to put your weekly mileage into 3 categories i.e (1) Miles slower than MP (2) Miles @ MP (3) Miles faster than MP; what would a typical breakdown look like?
Is this reasonable?
60-70% of miles slower than MP
15-20% of miles at MP
15-20% of miles faster than MP
