Some Quotes from John Hadd email send for me. I hope that youi wilol be able to get a better understand about Hadd distance training approach.
(…) On the 2 kinds of runners Cabral showed that there is more than one single way to get achieve this high aerobic conditioning. (…)
(…) Hi Antonio,
I like intervals, in fact, I love intervals... What I call a "FT" guy (more Mamede than Lopes who I would refer to as "ST"), so he can make lots of lactate and tend to have to work very hard to improve on his distance work. I designed Phase I based on my own knowledge and experience of what is best just for FT-types.
Long long years ago I always used to experiment.
I used to love workouts of many laps of 100m fast, jog the 100m bends, but that was too easy because the recovery was too long. I experimented with 50m fast and 50m float and found it could really hammer on that ones and reach very high lactate values. Intervals of 150m hard with 250 float some could run all day because he could recover in the 250m jog...(...)
(...) I coached runners that loved running 400s, and could run 20 x 400m at 3k pace and over the years they could cut the rest down from 60 secs to 35 secs standstill.... but after this workout they would be bent over on the knees and have lactate coming out of the eyes! They would be so completely wasted I would forget the way home! LOL! (…)
(…) But... as you note, on their own intervals are not enough and they must be built within a careful structure. I keep FT types away from them for a long time until they have mastered some serious long rep LT work at 92% and 95% of 5k pace. Then I get them doing 400s, 600s and 800s at 3k pace. I tend to keep the recovery short for FT's so they don't be tempted to build too much lactate (because they cannot build lactate in the race anyway). With a longer rec, they will run them harder and build more lactate; so we are building up an energy system beyond how much we can use it in the race. So with short rec, an FT has to use their aerobic system more. (…)
(…) ST's I give longer recovery, because their anaerobic systems are so poor they need time to recover between reps. We need to make their anaerobic systems more powerful.... so sometimes I give them fast all-out reps with long recovery. (…)
(...) I want to communicate with athletes directly. True advice only works if it directly answers personal problems. Generic answers, or general guidelines are worse than useless. We believe in going from the specific to the general. So we will begin by answering that most important question; telling you what to do tomorrow. And then the next day, and the day after. And from there, over time, you will learn the general guidelines that are directly applicable to you (and no-one else). (…)
(…)And when I see intervals at 10k pace, I know for best results I MUST see short and active recovery. If it is done with standstill recovery, I know from experience, this will not work well (esp for FT) as an LTP session. With standstill recovery I know the anaerobic system will recover — like magic — in very short time and will play too big a part in the next rep, and the next one and so on. So there will be too much lactate in each rep for good lactate management.(…)
(…) One point we are going to have to get into is this, and it is vitally important. Just because someone is ST, it does not mean he/she must do ONLY LT/LTP type training. Absolutely not!
We can take this slow and see what we both think, but here is my opinion/experience.
I told you my wife is very-ST. Best performance always at marathon 2:36. BUT, the best thing I ever did when I met her was to make her into the best 800m runner she could be!
I did not say, oh, you are a marathon runner and let's go and do LT runs all the time. No! I said first you have a big weakness. When we fix your weakness, then we can go and do the more easy work and fix your strength (LT runs).
So, I expect you to tell me that Lopes did faster training than tempo runs. How fast I don't know, but with Mrs H we like to see 800-1k reps at 3-5 pace with lots of recovery (to allow anaerobic capacity to recover because this is weak in ST). When we can run 4 x 1200m at quicker than 5k pace (for ST) then all other shape comes easy, even for a marathon. If we have good 4x1200m shape, it is very easy to get in race shape for any distance.
If we do NOT have 4x1200 (or 5x1000m or 6x800) shape then ALL OTHER RACE PERFORMANCES WILL BE POOR!
So, and I prove this to myself with Mrs H, if you are ST and you want to race your best marathon, first you have to train to run 800m as fast as possible (for 2:15-2:18 marathon maybe 2:05 for 800m. For 2:32-2:35 marathon maybe 2:15 for 800m). THEN you have to train to run 3000m as fast as possible (and still keep near-800m shape). THEN marathon training is very easy.
BUT for ST on marathon raceday must be in near-3000m top shape at the same time! (obviously not for FT). (…)
