The Boulder County coroner says the IRONMAN athlete who died after the Boulder event died from dehydration and rhabdomyolysis associated with excessive exercise.
Brian Godlove, of Fairfax, Va., competed in the IRONMAN in Boulder on Aug. 2. He died three days later.
The National Library of Medicine says rhabdomyolysis is the breakdown of muscle tissue that leads to the release of muscle fiber contents into the blood. These substances are harmful to the kidney and often cause kidney damage.
Godlove was 40 years old.
Godlove's family issued a statement that said, "Brian Godlove was a beloved husband, father, son and brother who lived and loved life to the fullest, and reflected the very best of the human spirit. He will be profoundly missed, but eternally loved and remembered."
