Episode highlights:

(20:01) Recap of potential cardiovascular health effects: athletes who train high volumes are not at risk, races and high intensity training are more likely to be problematic, the emergent state of ultramarathon research

(27:20) Respiratory risks of racing ultras: chronically no different than other endurance sports, drops in acute lung function, most are not clinically significant, asthma or other conditions mean you start from a lower baseline and can experience clinically significant problems

(35:23) The renal system: UTMB health policy, banning NSAIDs, duration, heat, altitude, dehydration, and hyponatremia all compound, NSAIDs make everything worse, acute kidney dysfunction in ultras is common and generally non harmful, chronic effects are unknown
