• Rupp is a superb runner who has shown remarkable consistency and progress.
• Rupp has allergies / asthma.
• There are over-the-counter & prescription meds for allergies / asthma
• (I suppose) some of these meds affect performance negatively (drowsiness?)
• Are there allergy/asthma meds banned by IAAF because the boost performance?
• It seems clear that on high-pollen days Salazar feels their options are non-existent. I wonder why?
