You guys are idiots. Lactate threshold has been shown to be the best indicator of performance over every distance from 1500m on up (check Noakes' Lore of Running if you don't believe me). It also has the most room for improvement and this is evident in the fact the average age of lifetime PRs for distance runners is 27-28, a time when anaerobic power and speed has already started to wane, but when aerobic ability is still on the rise. Long term aerobic development is the single most important part of distance training. I thought everyone knew this. Have you guys never heard of Lydiard? Do you guys not know that elite runners typically run a lot of miles and have for decades? Beyond that, threshold workouts maintain aerobic fitness while doing other forms of work. Completely ignoring them allows aerobic fitness to crumble. Even Coe says this, and he was more of a speedwork kind of guy. If you look at his logs in Better Training for Distance Runners, you'll see he did primarily threshold work much of the year and maintained some threshold work even into racing season.
The OP said nothing about Daniels and seems to be just going off of how he was trained in high school. You guys seem to be illiterate morons who've never read a thing about proper training. I'm honestly stunned there are this many of you on a running messageboard.
To the OP, no it's not normal, or if it is, there are a lot of bad coaches out there. None of the successful programs I've read about or had friends on train like this. I suspect your team is not very good.
