As I continue to research I will post more information concerning blood clots, deep vein thrombosis and pulmonary embolism AND how they relate to endurance athletes. Please take time to read at least one of these articles/blogs to understand how to prevent these from occurring and what the symptoms are.
They can develop after hard training sessions if you sit in one place for too long (at an office, in an airplane, in a car, etc.) or from the physical adaptations of being an athlete. Endurance athletes especially tend to have lower heart rates which means slower blood flow and we tend to push ourselves to a point of dehydration (thicker blood making it harder to the heart to pump, and being pumped slower). These are just two factors that can make an athlete more susceptible to blood clots, compound that with how often athletes travel and the risk increases. Here are a few great articles/blogs on the subject.
