Looks good to me for what it is, which is a speed/power increasing program suitable for experienced cyclists who are training to race - in my opinion. For a new rider, I'd like to see a program that worked more on the fundamentals of pedaling and more varying states of intensity. For winter, most folks work on the fundamentals and on endurance miles. I don't really start interval training until about February, though I always get some pretty good informal intervals on my weekly group ride. If you keep up with this program for more than 12 weeks, I think you may burn out. 12 weeks from now is January. Is there a reason that you want to be at peak fitness in January? Because you can't maintain peak fitness. Fitness should usually be going either up or down. OTOH if you ski, you'd be killer on the bumps with this program. Do this and then take a couple months off to ski and then repeat for the summer cycling season.

When I was in school, I just rode my bike as much as I could get time for, and mostly rode in the hills. Hills are automatic interval training. As a young person, I enjoyed the unstructured nature of just riding my bike and seeing what was around me. I got plenty strong.
