So, why is the only MLB team president to participate in the Ford Ironman World Championship getting so much media attention? That’s in part because Marlins President David Samson didn’t actually qualify for the grueling endurance event that consists of a 2.4-mile swim, 112-mile bike ride and 26.2-mile run that must all be completed within 17 hours.

He’s what’s known as a “media athlete” – one of a select group of up to six special invitees, who are asked to participate based on their position, background, or condition, according to Blair LaHaye, a race spokeswoman. For example, Jon Blais was an invitee who competed last fall, despite having Lou Gehrig’s Disease. The special invitees do not impact the number of athletes who qualify for or win a lottery slot in the race, LaHaye said.

They are chosen, LaHaye said, because they can help bring exposure to the event and the Ironman brand. Samson is also competing to raise money for two charities: the Florida Marlins Community Foundation and the Challenged Athletes Foundation.

Invitees must “validate” their spots by competing in at least one Ironman event of 70.3 miles or greater. Samson completed two 70.3 events before heading to Hawaii for Saturday’s Ironman competition.
