I was going to post a link to the article if it were not already posted.
Cesar, I think that one might be able to manage such a schedule by listening to your body and remaining controlled in your workouts and races. He addresses it in the article in the section titled, Endless Season Intensity
This isn't a phase where you hammer any and all workouts and races; this phase is about keeping things controlled, both in workouts and races. It's about consistency and self-control. It's a long-term approach, an approach of letting the fitness come to you instead of trying to force the issue.
I really like the phrase "letting the fitness come to you". Hindsight being 20:20, I see that most (maybe all) of my injuries have occurred at times when I was anxious to be race fit right now -- where race fit
represented a specific performance goal. I would suddenly start training at the volume or intensity that I thought would be necessary to be able to meet that goal -- right now. That doesn't work. You cannot get from point A to point B without passing through all of the intervening points first. You may never get there, but if you start training at the level that you body can handle now and gradually progress, there is a good chance for success. Magill states it well in his article, Slower Is Faster
I really like the idea of the endless season. My work schedule remains consistent year round. When I've wanted to try to train in Lydiard-style phases, I always struggled with the transition from one phase to the next and failed at some point in the progression. It is easier for me to establish a weekly routine and try to stick to that year round with only minor adjustments from time to time. I printed out this article for reference after doing little more than reading the title and skimming through the first page. This is exactly what I am trying to accomplish with my training.
I feel like these lessons that I'm learning in my 40's are things that others here learned much earlier. I've not been a very good student of the sport. Early on, I relied upon coaches to tell me what to do without understanding why. Later, I did do some reading, but I allowed exuberance to override common sense much too often. Hopefully, I am figuring it out while I've still got a some fast performances ahead of me.
