I run every day (every second day is only a short recovery jog), and work out 5 times per week: 2 x upper, 2 x core and 1 x legs. All focused on improving my running and reducing injury potential, so only calisthenics, no weight training. I don't do workouts the day before and the day of my long run. It's doable, once you find you routine and have separate deloading weeks for running and workouts.
