I did like the breakdown for this. For marathon volume they would probably change it to longer reps (recovery dependent on other factors)
In the sample training week provided in the paper, the four threshold interval workouts are:
-Tuesday morning: 5 x 6:00 at 2.5 mmol/L with 1:00 recovery
-Tuesday evening: 10 x 1,000 meters at 3.5 mmol/L with 1:00 recovery
-Thursday morning: 5 x 2,000 meters at 2.5 mmol/L with 1:00 recovery
-Thursday evening: 25 x 400 meters at 3.5 mmol/L with 0:30 recovery
For that last workout, the authors report observing “international level distance runners” running the 400-meters reps in 64 seconds while keeping lactate below 4.0 mmol/L. That’s just over 4:16 mile pace, which is quite a bit faster than what we usually think of as “threshold,” even for top runners. But the interval structure keeps it from becoming a sufferfest that will take too long to recover from.
It was discovered way back in the 70s that you could run a large number of fairly fast, short repeats with very short rest and still keep lactate levels low.
