Dude, totally commend you on your weight loss, but looking from the outside you’re falling quickly into a case of over training because you simply are not at a level to sustain things.
You appear to have read all the very sound advice above and then just thrown it out the window.
You will have much much much MUCH better results by simply doing the prescribed TR low volume plan and that’s all. Tooling around on Zwift is absolutely not the same as completing TR workouts. Do not add rides, do not take away rides. Just do the three rides a week for eight weeks and YOU WILL HAVE NOTICEABLE GAINS.
Are you a coach? Can you prescribe your own training regime? Do you understand fatigue? Do you know that the most beneficial aspect to a training program is… REST?
Your body is simply not at a stage to handle three days of TR plus extra racedays.
You need to lay the foundations of your fitness first. I know it’s boring and seems like a waste of time and you can’t see a tangible result such as beating Harry, Larry, or Gary finally. But Harry, Larry, and Gary all put in the base, all put in the rest, and that is why they are ahead of you. Not because they are riding 8 hours plus a week. They can only ride 8 hours plus a week because they first put in structured riding over 3 or 4 hours a week.
You dig a ditch to pour concrete into to build a foundation. Then on top of that you build a wonderful home with an attic window looking over a mountain landscape. Your problem is that you are building a rickety ladder to try and attain the same view without digging that ditch.
Trust in the Trainer Road program. Trust in low volume. Don’t add rides; the intensity of TR is too high for your body to cope with currently when you do that.
Step back. Be realistic.
You will get there, but not by simply cramming in more riding and thinking if I ride more I will get better. That statement is simply not true when you follow a program like TR.
TR is all about quality, not quantity. Trust in the Chad. The programs work IF YOU FOLLOW THE PRESCRIBED VOLUME AND INTENSITY AND REST VOLUME.
I know the above sounds very blunt, and it seems like you’re mad keen, which is great! But also be realistic. I’m afraid that you simply are not currently.
TR is a different tool to Zwift. It’s even a different tool to riding outside. And as such, you have to use that tool differently.
You will still get fitness benefits on three days riding. Actually you will probably get much more than 3+1race+1freeride. No, strike that. You WILL get much more than 3+1+1.
Good luck.
