Still Rolling

I started my second week of Base 3 with an easy hour ride this morning.  Twenty five minutes in Zone 2.  The rest in Zone 1. 

Tonight, I have a 2hr cruise interval workout planned.  I am going to try to do 4 x 12min Zone 4 intervals.  In the training bible this workout is listed as a Muscle Endurance workout but to me it feels more like a aerobic endurance workout.
