Hello
I am a 24 year old female distance runner who ran mainly the 5k and 10k in college. I have a 35:00 pr in the 10k. Over the last 14 months I have not been able to run at the intensity I used to be able to. The main symptoms I am having is severe fatigue. I can run some days at an ok pace but other days i can barely run 8:00 minute pace without my body feeling exhausted and feeling like I just completed a tempo run. My body also gets achy and completely shuts down when I try to do any type of faster workout. After running for 3-4 days straight I cannot do any type of physical activity without getting exhausted and my heart rate shooting up. I have gotten every blood result done with them all coming back normal. Was just wondering if anyone has any ideas of what could be going on. Again this has been a constant problem for the last 14 months. Any help would be much appreciated. :) thanks!
