15 miles 2:22:56 Felt ok up to mile 10, then it was like I just wanted to lay down on the nearest patch of grass and sleep. The last 5 miles dragged :-(. I think my friend is probably right... perhaps low iron is to blame? I did some research and I guess it is very common, especially among female runners and vegetarians (I'm female and pescitarian - a.k.a. "fish-atarian") to experience anemia and/or iron depletion (low ferritin). I guess low ferritin often goes undetected when getting a simple iron test because doctors are usually looking for hemoglobin and hematocrit levels. The problem is both of these levels can be normal while the ferritin is depleted and which can make a huge impact on running performance. I think I'll head in for a serum ferritin test tomorrow and in the meantime, I picked up an iron supplement today. Anyone with suggestions or experience on this... please share. |
