Question: how do I avoid over training? I am upping my mileage by 1/2 mile each week and am up to 8 miles for my long runs. When I started training six weeks ago I was at a 15 min mile, I am up to 13 min mile, and will continue to work on pace. I guess my question is what else should I be concerned with, I am afraid to back off on long runs, but know that I will be at 13 by Thanksgiving with way too much time before the half. Given the uncertain weather for January and February, here in the Northeast, outdoor runs may become an issue. OR, am I stressing over nothing?
