Well, I wish I could do aerobic intervals, but I have a tough enough time just running and staying below MAF. I can do it for about 10 miles, but I am right at 12:00/mile. So, at this point, to do a MAF-10 I'd probably be walking.
This statement alone probably answers my original question. I probably shouldn't be throwing any anaerobic training in just yet. But, I don't think going over MAF every few weeks will kill the base building. In fact, it appears to help my MAF Pace. Now, I wish I could try that out, but I ended up with a chest cold after my last run (damn kids). So, no running for me for a few more days.
