Last year I got really wrapped up in total miles, but have since learned that focusing on hours with all aspects of working out is more effective and more important in building and maintaining fitness. I terms of my actual workouts in the plan, the biggest difference I am making (at least in the early base and build phases) is the addition of strength training. I did no weight lifting last year in the early months and found myself suffering in the middle of the summer on short steep climbs. I focused on strength a little for the cyclocross series, and found it to be very effective at improving my force and power as the series progressed. Understanding this need for strength will not only make me physically stronger, but will help with my endurance also.
Finally, the only thing I have left to do is schedule weekly workouts. Which I will do on a week by week basis. The beauty of the plan is that although I have it all written down, It is and will remain flexible. Sometimes life gets in the way. So the need to skip, change or eliminate training days or races is bound to happen. And as I am moving up into Cat 1 (expert) in mountain biking, this will be a very challenging and learning year for me. So I will soon know if my plan is right on, or if I am way off. But that is the beauty of it, as I continue to learn more about training and how my body reacts to the stresses, I will become more effective at making the correct changes and will become a stronger racer in the long run.
