You are sore. You are doing too much volume.
There is a balance to learn. If your goal is running then you have to figure out the type of lifting that results in increased strength without unnecessary soreness.
Let's say your 5 rep max for a front squat is 135lb. Try this:
set 1: bar x 10, 60s rest
set 2: 95 x 5, 120s rest
set 3: 115 x 5, 2-3min rest
set 4: 135 x 5
The following week aim for 6 reps on the last set. Once you can do 6 reps, add 5lbs on the next workout and try for 4 reps. Next workout go for 5, then 6, etc. So the progression is auto-regulating. You stay in that 4-6 rep range. As you get stronger changes become harder to make and may take weeks, or you work on the quality of the rep, or you move to a 3-5 rep range.
