Whoops! I think the abundance of added un-subscribed volume here can lead us to conclude that this is less of a ‘burnout’ from your training plan, and more a self-induced fatigue (mental and likely physical) from tacking on a bunch of extra endurance.
I don’t think doing less than the three key workouts assigned in a Low Volume plan is the key to helping you get faster. Those are super key systems that are very intentionally assigned, so missing one crucial workout a week wont set you up super well for success.
I think its possible that you like to add all that volume because you love to ride, and thats okay! We can make that work, but it also means you need to do your due diligence in making sure you’re setting yourself up from a nutrition, recovery, and rest aspect to handle a higher volume.
Finally, that mental burnout that you feel looming is synonymous with any training and coaching experience. From my very first season doing structured training to even now, there are times when having to do structured ‘work’ on the bike almost every ride feels so cognitively taxing. Its normal, and it means it may be time to do something fun off-the-bike and sub out some short endurance chill/fun rides for your workouts if you need a mental reset after your C training event.
Take a little bit off that extra unstructured endurance, recalibrate and refocus on recovery/nutrition/everything that goes along with ‘high’ volume, and check back in to let us know how you’re feeling afterwards.
