Hi devolikewhoa83,
Congrats on the sweet new bike!
The Base plan is designed to progressivly increase volume and intensity will ease you back in. The test is an important part of getting your training intensity correct. Your power levels will be lower after a season break and restarting with accurate lower power levels is an important part of easing back in and building back up to peak performance. None of the training in week 1 of the Base plan should “slam” you if you have your power levels set correctly.
