So, last time we were talking about iron deficiency--what it is, and why runners (especially female runners) might care. You can read Part 1 where I discuss my first experience dealing with iron deficiency & some things I learned about it here.
All caught up? Excellent!
Fast forward to about a month before the Boston Marathon. In my first couple months of training I felt amazingly good--workouts were easy, and I had no trouble hitting the mileage. After that (as you know if you've been following along), I had some injuries and got really sick one week, so I would never in a million years have thought that I was training hard enough to mess with my iron levels.
Still, I kept getting that same feeling I remembered from when I was training for Eugene; just exhausted all the time, hitting workout paces starting to feel way, way too hard (and for the first time I can ever remember, sometimes actually impossible), and that sleep-deprived/low-blood-sugar, knock-me-over-with-a-feather feeling while running, even just on short easy runs.
For a while I was chocking it up to stress, losing fitness from all the missed miles, and maybe just getting old. But chatting about it with Don one day, he was like, "When was the last time you had all your blood work checked? Could it be iron or thyroid or something?"
