This plan should be done after off season strength work and before race season or when you'd like to be in peak shape. The overall volume builds throughout the plan as well as the volume of steady state(near threshold) intensity. The volume of leg focused lifting sets per session is adjusted based on the goal for the week. This plan is suitable for most disciplines of cycling including road, mtb, gravel, cyclocross, etc.
The difference between this plan and the other base training plan is that the intensity during the endurance rides varies in order to keep you interested while riding on the indoor trainer. The long rides are also split into two rides. There is not a physiological reason for these changes, it is just to improve motivation while stuck indoors. If you have the opportunity to do an endurance ride outdoors then ride for the same duration at 55 to 75% of FTP and ignore the intensity prescription.
As always the plan is simple, easy to follow, and based on research, not assumptions. Everything you need and nothing you don't.
I'm a cycling coach based out of Brevard, NC as well as an elite level ultra endurance mountain and gravel racer.
My coaching philosophy is simple: follow the best available balance of evidence. I try to base my coaching decisions on research, not assumptions. My training plans reflect this, they are simple and easy to follow without a lot of bells and whistles. Essentially everything you need and nothing you don't.
