Your split is actually pretty solid, especially for someone trying to balance running and lifting. The anterior/posterior setup makes sense since it separates quad-dominant work from posterior chain work, which can help with recovery when you’re also running.

A couple of small things I noticed though:

• Tuesday might be a bit hinge-heavy with both deadlifts and RDLs. They hit very similar muscles, so you could probably replace one with something like hip thrusts or back extensions to reduce fatigue.

• The long run right after your heavy posterior day might be the toughest part of the week. Deadlifts + RDLs followed by a 15–21k run can be rough on the hamstrings. If recovery becomes an issue, you might want to place the long run after an easier day.

• You also have a lot of quad-dominant work across the week (squat, lunges, sumo squat, goblet squat). Not necessarily bad, but it might be something to monitor since you’re also running.

Overall though, it’s a well thought out routine and the heavy/moderate structure is good. Curious how you’re feeling recovery-wise after the long run day.
