It depends all depends upon how much glycogen you spent during your workout.
When doing cardio, you first use up muscle sugar then stored sugar then once glycogen stores are depleted your body's burning of fat greatly increases. Depending on your intensity they say that this starts between 15-20 min of cardio.
BUT, if you have already depleted much of your glycogen stores during your lifting, your fat-burning would kick in earlier into your post-workout cardio.
On days that you are only doing cardio and not lifting you want to make sure run for a longer period of time. You want to get past that first 20 min to start burning fat. Limit the cardio session at 60 min though.
