Daniels "alien" HM plan. Has anyone done it?

More info, please.

The two, 7-day cycles include 3 quality sessions per week.

The first week the sessions are a long easy run, a threshold session and a repetition session.

The second week includes a marathon-paced session (40-100min), a threshold session and an interval session.

For the threshold, interval and repetition sessions the athlete picks the exact workout based on their weekly mileage.

Seems fairly standard, just not sure if anyone would see an advantage of this over traditional 10K training with a bit more volume.

I've trained similar to this. week1:

Tuesday 4x10 min or 3x15 min or something similar at marathon pace

Thursday 1000s and 200s or 400s at threshold/3k-10k pace

Saturday long run

week 2:

Tuesday 10x1000 threshold

Thursday 200s or 300s at 3k-5k pace

Saturday: 4x8 min threshold

I had my best results on the 1500 and 5000 with this training, 3:38 & 13:26. I think it worked for me because while the long marathon sessions & long runs work well for me, doing them too often wears me down a lot.
