So i started to train this way and i think it is a great method. I have a race in 2 months, so then I will see the first results.
What I really like is the simplicity:
25% LT work = intervalls with short rest
Pick: 20x400, 8xk ,3x2k ,2x3k
75% Daniel E pace running
No peridisation, no drills, no complicated mixed workouts.
For the guys complaining about lack of speed work, Nobody stops you from:
A) Adding a day of strides/ hill sprints, if you do it the Norway singles is quiet similar to Hudson or Pfizinger type of training plan.
B) Or just increase the speed of one of the last reps.
20x400m @ 10k -> 16x400m @10k + 4x400m @ 3k
8x1k @ 15k -> 5x1k @ 15k + 2x1k @ 5k + 1k @ 15k
C) or replace one of the sessions with hill reps
D) Replace some sessions with races or time trials
Personally I think option B) or D) are best, but the truth is this:
Speed work only matters if you have a shot of winning the race, so why bother if you cant hang with the lead pack for the first 3/4 of the race.
First you must be aerobic fit and that is done by milage, tempo and treshold running and this is what this method does.
I am sure Vo2 max , hill sprints and plyometric jumps are great, but I am just a middle aged overweight hobby jogger trying to break 38min in the 10k, speed is just not my limiting factor.
