Reverse order. Run early lift late. Also, better to do both on one day so hard days are hard and easy days are easy. Having hard runs and lifts opposite of each other never allows for the body to recover.
Sorry wrong, lift first, run later. Assuming your goal is to increase strength, you should lift first, many studies have shown this is optimal. Alex Hutchinson and Steve Magness have blogged on this, Alex even wrote a book: "Which comes first, cardio or weights" in which he directly answers this question. The problem is, aerobic exercise down regulates the hormones/enzymes/physiological processes that rebuild strength, in short, aerobic exercise is catabolic. Starting off with strength training upregulates, for the day, the strength building aspect of your body. Maybe if you ran a 20 miler in the PM it might down regulate, but maintenance cardio should not.
If you're just lifting weights to burn calories and stay lean, it doesn't matter which you do first.
Let me put it another way, body builders know all the tricks, and they will do there shredding/fat-reducing cardio in the PM, long after strength training.
