This is the Perfect Base Plan if you have around 10 hours per week to train. When it comes to base training there are two things that every cyclists really needs: Frequency and Intensity. No matter which study looks at maintaining endurance performance, frequency and intensity always come out as the winners. Therefore, I build my plans on the study from Ronnestad that looked at maintaining performance during the transition phase. Essentially, you need some basic intensity or you get dropped.

Another factor that plays an important role is strength training. And again Ronnestad is the scientist that researched the field for endurance athletes. As their's no racing during base training it's a good time to add strength work. I've taken it into account and put strength sessions in the plan.
At the end of the plan Critical Power Testing will give you a performance baseline to transition to the Build Phase successfully.
Considering the aforementioned, with this base plan you are primed for being a faster bike rider. Have Fun!
