NYC based CG Sawaya Partner banker Slava Leykind dies in Wyoming doing Mount Everest challenge

A Big Apple banking executive and father-of-three died after quickly hiking up and down a Wyoming peak six times during an “Everesting” endurance challenge.

Slava Leykind, 43, of Westport, Connecticut, went into cardiac arrest after competing in the event at Snow King Mountain in Jackson Hole late last month.

The endurance-style event sees hikers repeatedly trek 1,500 feet up the mountain to match climbing Mount Everest — the world’s tallest peak at 29,032 feet.

Leykind managed to complete six laps before first responders were called in and he was rushed to the Eastern Idaho Regional Medical Center in Idaho where he died on July 2, Jackson Hole News & Guide reported.

His cause of death was a “an electrolyte imbalance causing cardiac arrest,” the Teton County Coroner said.

Leykind, who lived in Westport with his wife and their three kids, was an exec at the New York City-based investment bank, CG Sawaya Partners, where he’d worked for two decades, according to his LinkedIn.

“Despite his significant professional success at a young age, Slava’s role as a husband and father was his greatest achievement, passion and pride,” his obituary said.

“He fervently supported his children, bringing love and a sense of calm to the wonderful chaos of a full house.”
