To augment Susan's response; I totally agree that it depends on your race goal... I wouldn't suggest going from running 2-3x a week immediately into running 6x a week all in one step. Good way to get a stress fracture in a foot, among other things.
You are already having to augment Hal's plan by joining it in the middle, so transition into it slowly. This week run 3x. Next week 4x. 3rd week 5-6x. Then stick with the plan.
Obviously, this means that during the 3 transition weeks, you have to delete a few of Hal's suggested runs. Make sure that one of the runs you do is the weekly long, slow run (unless it turns out that Hal has put a 'rest' week in the middle where he drops back on mileage... pretty common). This is the most important run.
Also, talk to your doctor about running w/ a broken collarbone. it can be done, obviously... however, if you are a very bouncy, rough runner, then it may be uncomfortable. Worst case is that it will take your body longer to heal. Take it slow.
