I felt a bit meh during my last few #running races. Could not push hard on uphills and constantly short of breath. So I went to get my blood tests done. #Anemic. Very low iron levels. Very low #hemoglobin. Explains few things. Scheduled on iron infusion and bought 100mg(!) Iron tablets plus #Vegan multivitamin complex.
Don't be like me. Get yourself checked regularly to make sure.
