In 2020, 67-year old Tom Butts spent 110 days in the hospital with COVID-19. He was fighting for his life on a ventilator, in a medically-induced coma at Kaiser Permanente San Jose. Tom left the hospital 110 days later weighing only 97 lbs. As a lifelong triathlete, Tom was used to pushing his body to the limits in fitness training, but he knew that if he ever wanted to run, cycle, or swim another mile, he’d need to train like never before and learn to use his lungs again.
