Good work diving into the training and process of improving your aerobic capacity. It looks like you have a good template laid out for the week which covers your bases. I wouldn’t be concerned right now about the “missing” 15% running volume, which you’ve chosen to replace with the bike ride. For right now I imagine the gains you’ll make by spending lots of consistent volume at your defined AeT will be the most important. As you progress and see that base growing, and/or if you get an objective (such as a 50km race or similar) on the calendar which will require getting more specific with your running, you can shift that bike ride to a run, and opt instead to use the bike for other days. I will often program a recovery 30min bike ride after strength workouts for athletes; this is an easy way to get “extra” volume in a non-impactful way, and without diminishing the running volume.
Hope that helps – good luck!
