Do you have a question?
While we're at it...if you do have a question, you will likely get better advice in response if you include more detail about yourself than "Workout 6 days a week. Running and weights>"
How old are you?
Height and weight?
Balance of lifting vs. running?
What kind of lifting?
Goals, in particular, tend to be a sticky one so let's discuss that for a moment. "Looking to build lean muscle" is a very vague goal. However, if you let us know that you're 6'1" and 170 pounds, lift 3 days a week and run 3 days a week, and have a goal of getting to 185 pounds and adding 20 pounds to each of your big three lifts while maintaining your 5K time...now we're a little more prepared to give some useful advice.
What kind of lifting, too, is important. Another thing that seems to happen a lot here is someone says that their "program" is Chest on Monday, Biceps on Tuesday, etc....more specifics. What exercises? Sets and reps? Weights used? Progression?
