The upcoming 2011 season will be my first racing and training with a strict plan and performance goals.
I have put together an annual training plan using Joe Friel's "Cyclist's Training Bible". I'm excited about having goals and a structured plan to achieve them. Because I have taken only a very short layoff after my cycling season I am starting the plan with a good foundation of fitness. I have some weight to lose and plenty of room to improve power and performance at every level but I also want to make the best use of my time. I'm questioning the strong focus Friel puts on L2 work during 12 weeks of base training. I have both weekend days free for long rides (anywhere from 6-12 hours over 2 days) which I feel is more than adequate to maintain my aerobic endurance, and plan on 1-2 hours in the mornings 4 out of 5 weekdays. It seems to me that doing mainly L3 and adding in L4 on some of those weekdays would better. I don't see the benefit of 2 hours of L2 when I can put in 2 hours of L3 or a 4x20 session at high L4, except that 4x20s leave me blasted the rest of the day.
Am I missing something important here? Looking at Dr. Coggan's chart of physiologic adaptations that take place according to different levels I don't recall any changes that L2 stimulates that L3 doesn't.
For what it's worth the training plan does incorpoate higher intensity in later phases. And, the races that I prioritize the highest are hilly road races and a stage race (TT, crit, and RR) though I also look forward to hill climbs and TTs. I've several crits penciled in as well as some circuits and flatish road races, but these are races where I'll be gaining experience or points to upgrade, or working to help a team mate.
