The plan(s) I’m about to provide you each use the same methodology, which is genius, and brilliant in its simplicity. A 36min runner should be able to execute it (I.e., it should work, if followed. Again, if you are unable to follow it, then you are not adapting fast enough, and you will need to dial back expectations, and paces, and it will thus, take longer than eight weeks.)
This plan is backed up with years of scientific research that culminated into the following two key online calculators, combined, upon which this plan is based:
1. Jack Daniels Calculator;
2. Tanda Calculator.
With their clear understanding, these calculators provide the requisite volume and pace for practically any level of runner.
Three different mileage plans are provided below, as examples. They are to be followed for at least eight weeks. Each gets one to 36min capability.
45 mile week plan to 36min capability:
Every day, run 3x2mile reps, at 6:02/mile average. On one or two days of the week, add in an additional 2mile rep to get to 45miles/week.
50 mile week plan to 36min capability:
Every day, run 3x2.25mile reps, at 6:13/mile average. On one or two days of the week, add in an additional 2mile rep, as necessary, to get to 50miles/week.
40 mile week plan to 36min capability:
Every day, run 3x2mile reps, at 5:50/mile average. On one day of the week, drop one of the reps to total 40miles/week.
Alternatively, run only 6/days week but add an additional 3x2mile rep on a couple of the other running days in the week.
Take sufficient recovery between reps (e.g., walk 400m.)
To make this plan easier starting out, you can run 6 one-mile reps instead of 3 two-mile reps per day.
