I don’t think 2 x a week is a good workout. I seem to recall reading somewhere that strenuous 2 x week workouts can be stressful on the body vs how much benefit it offers. Note: twice weekly modest workouts are very helpful.

Try reducing the length of the run and/or substituting fast walk warmup and cooldowns, and adding a gym or some other workout to bring it up to 3x workouts in a week.
