What Causes Headaches And Nausea After Running?

I have run a few 1/2 marathons, and 1 full. Training for a 1/2 now and have had 2 episodes of light headedness, nausea during two training runs - 1 mile into one, 3 into another. No pain, just feel like my heart is racing and I have to sit down. Any ideas?

There could be a variety of things causing your symptoms from the more obvious things such as dehydration and hypoglycemia to things that may be more subtle and less likely in someone of your training ability and skill such as cardiac abnormalities from either conduction defects or valvular disturbances. Your first stop should be to your primary doctor to get a good physical checkup and if necessary laboratory workup. Your 2nd stop should be with either a cardiologist or doctor specialized in exercise physiology and training (perhaps PM&R) to either do detailed EKG and Echosonographic studies, a STRESS TEST, or what I would consider a HOLTER or event monitor to be worn...especially when engaging in heavy training runs or better yet a competition. That's where things will become more apparent in terms of symptoms.
