The sweating thing is interesting, but I've always done lots of sport (not necessarily running) so sweated a lot (!) and never had low iron... I suppose I was curious about whether there is something particular about hard running training that affects iron levels?
I know elite athletes esp. women are more prone to anemia, but not why....
I've been a regular blood donor for 10 years and never had any problems. I gave blood last november just before starting training for london as my first marathon... went back today and got sent away as my iron is too low!
My diet is good and I eat plenty of iron rich foods. I seem to remember reading once that increasing training can reduce iron - does anyone know if this is true?
Just curiousity really, as I feel fine otherwise. thanks! EB
