Tuesday 10x3min (Or 7-8x on easy weeks), Thursday 5x6min(4x on easy weeks), Saturday 3x10min(or 2x 3km on easier weeks). Easy days are Monday, Wednesday and Friday, but each 2 weeks I skip the run on Monday to completely reset and feel fresh for next Threshold interval. On Wednesday and Friday I usually do strides at the end of the run 6 short ones 15-30sec. Sunday as a long run is 75-90min, running just a little faster than easy runs.
I did about 200 lactate tests earlier this year, wasted first 50, just to get a feeling on how the lactate behaves. Most of the test were done on with the intervals I still do. But last 2 months I did not do any lactate testing. I don't think it is necessary at all to implement this method. Just be honest with your self and especially when starting, be safe with the pace to not get over the threshold. Like Marius Bakken wrote, if you go over the threshold by 10%(Probably LT2), you get 4-5x more fatigue than staying 10% under it. That's the whole point of this method.
I think the paces I hold in intervals can be summed up as the 3min intervals at a bit faster than half marathon pace(around 5 sec per km), 6min intervals at half marathon pace and 10min intervals at pace a bit slower than half marathon pace(5-10sec).
But you have to be honest with those paces, and not take the PR that was set on optimal conditions 2 years ago. If you don't feel fresh and struggle to hit all workouts, you are going 2 fast.
If someone is doing about 60-80km of training, I am pretty sure they can pretty much jump right in and try this. Maybe start a bit safer by cutting a few intervals on first few weeks.
I was injured around hip area for 1 year, so my stride was compromised a bit over the past year. I think my running technique was pretty bad and I was not utilizing muscles in top parts of the leg at all. I think I fixed that by adding in Zwift rides, about 3-5 hours total every week. I think a bit of cross training has huge benefit and can increase load which would injure you if it was done with pure running.
It's pretty clear my CTL is through the roof since I started following method of training.
Right now I am tapering for the race on Sunday
