Ehh, yes and no. Lifting hasn't helped me much with distance running, and vice versa, but it has helped quite a lot with sprints. Especially, if you run sprints in the hills.

Running more than 5k in a run, will strain your muscles more in endurance way, and if your main goal is gains, not cardiac health, then don't run long distances. For me, I have observed, if I increase my running distance, up to 10k in a run, I do worse in squats, but I can do more split squats and other stuff. What works the best for me, is variety in my leg workout. Currently, I run sprints once a week, and 2 times a week I jog. I have 2 leg days in the gym, and in those I do Bulgarian split squats, pistol squats, hip extensions, glute-ham raises, leg raises, skip with skipping rope, jump on stuff, do static squats, do some resistance training with leg extensions, using resistance bands and balance platforms, do reverse cycling, on a mechanical bike, and do front squats, and my legs feel amazing. Last week did 30km hike in couple of hours, with 0 prep, and had no problems at all.
