As fall training and race season pick up, we wanted to share something many runners don't think to check: their iron levels.
Iron deficiency is one of the most common blood conditions we see in endurance athletes. It can leave you feeling unusually tired, slower to recover, or like your legs just won't cooperate, even when your training is going well. Studies on marathon and half-marathon runners have found this is especially common among women, though men can be affected too.
The reassuring part is that a simple blood test checking hemoglobin and ferritin can identify low iron stores early, and treatment is usually straightforward once it's caught.
If you or someone you love is training for a fall race and dealing with unexplained fatigue, our hematology team is happy to help. Call us at 856-890-7200 to schedule a consultation.
