Yeah, no… don’t cram like your example above (I know you are planning to change, but this is almost NEVER a good idea).
The short and sweet answer is to ignore what you missed last week and just move on with the existing (original) plan without shoving in “extra-credit” to make up for last weeks losses. Trying to cram that may well lead to excessive fatigue and eventual poor performance in one or more workouts of the week.
I would likely reset to the actual plan week and maybe include an easier Endurance level ride to increase TSS gradually for the current week. Mid volume is no joke for most people, so be cautious of taking on too much because it may bit you hard in the following workouts and weeks.
