I'm going to be a senior in high school (16 years old), and I recently got a blood test done. My hemoglobin level showed 9.8, which I know is very low (average/healthy supposed to be 12?). I've started taking iron supplements, but my question is does having low hemoglobin levels mean my iron levels are also very low (I didn't get an iron test done)? I know that low iron levels would keep you tired, unable to run well, etc. but I dropped a lot of time this season (5:47 to 5:14 in the 1600) and I'm running around 40-45 miles per week right now, hoping up to build that closer to 60. I've been feeling "faster" on my runs as well, as opposed to a few weeks ago. It seems like I've been improving, and I haven't really been feeling dead/extremely tired, so I'm not really sure how I dropped so much time etc when it turns out my hemoglobin level is so low. I was wondering if anyone knew the explanation to this, etc. Thanks a lot!
