Heavy training and periods together drain iron like a leaking bucket, yaar, and coaches should push for ferritin above 50, not just the lab's 'normal' 15. I was that runner, feeling tired all the time but pushing through, thinking my willpower was enough. My downfall was winning a 10k race with ferritin at 20—I collapsed at the finish line and couldn't run properly for months afterwards.
