Hi Shaka,
I can share with you my standard training week from my marathon training this year, if it is interesting to you.

Monday: 12-14km Easy run with strides
Tuesday: 12-14km Easy run
Wednesday: Cruise intervals (8x1km, 4x2km or 1-2-3-2-1 pyramid) ~12-15km total
Thursday: 22-28km Medium Long run
Friday: 7km Easy morning run / 7km Easy evening run
Saturday: Long run 30km+ with some quality
Sunday: 5-10km Easy run

For me easy means less than 75% of max HR as my HR average.
Every 4 weeks I take an easier week down at about 70% of the mileage I usually do.
That is what I do, it obviously isn't perfect, but I think is a decent outline of a plan.
