Just saw this...do the headaches only happen in the summer? If so it could be heat related and not exertion. Headaches like what you describe are a classic warning of heat exhaustion. Ate you drinking enough water before, during, and after your workouts. A good rule of thumb is 16oz before you workout...16oz for every 30 min during your workout, and then 16oz after your workout. Also, you can sub something like gatoraid or propel for some of the water to make sure you keep your electrolytes balanced.
