You want to balance strength training and running?

Be smart with your training structure. Lift on one day, run on another. Or do the running at a separate time of day. And try not to make all of your runs hard (most should be conversation pace).

Make sure you add calories. And more specifically, more carbs, to account for all of the training. Tough to perform well in a chronic deficit.

Lift heavy. 3-10 reps per set. You want to build strength and durability, and you’ll be hitting different muscle fiber types and energy systems than you hit while running. So easier to stack.

Get good sleep. 7-9 hours per night. If you read fiction before bed, it makes knocking out a lot easier. And don’t obsess over “optimal sleep” to the point where it stresses you out, and becomes suboptimal.
