I really like TR, but following the plans this year got me into a hole. I was completing all the workouts, but the fatigue kept building. Then I had some poor early season race results. I eventually got a coach that was able to build a plan that allowed me to get more weekly hours on the bike, but in a way was manageable and sustainable. Then the results started to improve.
A one plan for all isn’t going to work for everyone, and most people like myself don’t have the experience to recognize when things are going south. Mix in motivated individuals, and we’ll train ourselves into the ground. It sucks I have to pay for a coach to protect myself from myself, but that’s how it is.
