Would I benefit more from increasing my speed or the duration of my workouts?

As a cyclist and runner and treadmill runner for decades:
You are doing enough running for health and want to push your limits.
You can do a weekly distance trial, to gradually increase your performance. The beauty of the
treadmill, is the built-in display of speed, time, distance, etc. Even a 1-2% improvement goal each
week will eventually turn you into an animal. For example, 3.5 one week, 3.6 the next, 3.7 the next,
easy week, 3.7, 3.8, 3.9, easy, 3.9, 4.0 ... You can help this by doing some short faster pacing,
just to teach the body to move faster without pounding or other inefficiency. In recent times, I got
up to 4.3 miles in a half hour this way, and did 10 miles in 75 minutes, just with a weekly
increment.
You can also do a weekly longer run to push endurance.
It is quite common to use both. Typically, build some distance, a "base". Then, in anticipation of a
race, begin some faster and hillier training. By huffing and puffing for 20-30 minutes once a week,
you raise your AT. By doing sprints you improve VO2Max.
There are strong similarities to training by cycling but also some key differences: on the bike, I
can go to the limit of my legs, distance, hills, speedwork, pacelines till I get dropped, bonk, eat,
recover on the same ride and do this for many hours, etc., do this once a week for a half day, for
six weeks, and be in great shape. Running this way, I would be injured within a week or two.
In cycling, good form comes from maintaining a high cadence, developing supplesse, but you can find
many weekend cyclists who get a great workout with terrible form. Only about 25 percent of them have
sore knees, or whatever. In running, lack of form sidelines runners with injuries, more like 75
percent, as a rough comparison. You can do the equivalent of a "spin" while running to help protect
yourself. In particular, increase turnover to 180 strides per minute instead of 160 or 170, learn to
eliminate overstriding, to make almost no impact noise, no slapping, minimal vertical bouncing, no
exaggerated heel strike. In the gym, you can track yourself in the mirrors, and compare the noise
you make with some pounders nearby.
Running up an incline would be better training for cycling than on the flat, but be careful. I have
trashed my calf muscles many times by doing too much of this too fast. The optional "Hill Program"
on the gym treadmills offers a good compromise as it varies the incline during the run. Another
drill, if you work up to it, involves backwards running and walking. Walking backwards at 3.0 mph or
so, up a ten percent grade works the quads and helps the knees. Running backwards from 4.5 to 7.0
mph works the lower leg, somewhat like skipping rope.
