You may not know this, but you have opened a can of worms. I don't think anyone would argue that there's no need for a solid aerobic base. The point of contention on this an other forums seems to be centered around this statement in the article: "Pushing yourself towards the red zone negates aerobic gains during long easy rides."

I don't see how that could be pysiologically possible. I can see the concern for burnout, I can buy into the need to do some long rides, but I don't see how occasionally dipping into the red zone during a long ride could "negate aerobic gains." Obviously if you're going so hard that you can't ride for more than an hour you're not likely to build an aerobic base. But saying that you can't mix some intervals into a long ride at the risk of "negating the aerobic gains" seems like a hilariously indefensible statement from a scientific, physiological standpoint.
