Advice/Feedback on Running and Strength Training Routines

I am an intermediate level runner and I want to incorporate some regular strength training in to my workout routine. I run at least 3 times a week and more typically 4 and will gradually increase the distance over the course of the week from 5 to 8 miles each session so I'm running ~25 miles a week.

I am looking for feedback, ideas or advice on workout routines. My schedule doesn't allow me to do a split workout (strength in the morning and running in the evening or vice versa). Any thoughts would be greatly appreciated. I've done some initial research online but there seems to be a lot of conflicting information. My goal is to build a solid overall fitness level. I'm not a body builder but I would like to add some muscle. I really enjoy running so my hope is I can find something that will allow me to do both without one coming at the expense of the other.

Anyone have any experience with this type of program? Do you do both in day? Are you running before or after strength training (I seen conflicting advice on this), How are you breaking up the strength routine to hit all the major muscles?

Any feedback is greatly appreciated.
