Meet the engineers, doctors and clock punchers competing in the Olympics for Team U.S.A.

Former college basketball star Canyon Barry isn’t the only Olympian who has to balance 9-to-5 work with preparation for Paris. But Barry, a hoops scion with a bachelor’s degree in physics and a master’s in nuclear engineering, was probably the only Team USA athlete giving a high-level work presentation from Mongolia at 2 a.m. — the afternoon back home in Florida — last month while he was also getting ready for the Olympics.

“It’s definitely a grind at times,” Barry, who plays 3×3, said in an interview that started 30 minutes behind schedule … because he had to take a work call. “I’m so fortunate [my employers] are willing to work with me. That’s part of the Olympic spirit to do whatever you can try to succeed and pursue that dream.”

Scores of elite athletes have to put on their work boots before they lace up sneakers to run down Olympic aspirations. Sports psychologist Mark Aoyagi said the laboring athletes face a uniquely difficult challenge.

“It’s not ideal, certainly,” said Aoyagi, a professor at the University of Denver’s Graduate School of Professional Psychology. “That’s particularly if you’re comparing yourself to other countries where some athletes don’t have jobs — they’re being paid by their government. When you’re a looking at a Russian athlete or a Chinese athlete being paid, it can be challenging.”

In stark contrast to glitzy promos touting star athletes that will fill airwaves in the coming weeks, many performers on the Paris stage will be unknown Americans who work full- or part-time jobs to support their high-level endeavors.

“How do you do it? Athletes are great at compartmentalization, keeping one part of their life and their experiences from another,” Aoyagi said. “From a mental and emotional level, that’s key.”

Barry, the son of NBA Hall of Fame guard Rick Barry, has a strict regimen: up by dawn for weight training and yoga, going to L3Harris Technologies headquarters in Melbourne, Florida, for work, then off to the gym for basketball training after he punches out of the office.

The long days, Barry said, aren’t too different from his time as a College of Charleston undergrad and a University of Florida grad student, having to make the most of 24 hours while he was playing NCAA Division I basketball and taking high-level STEM classes.

“It definitely required good time-management skills,” he said. “It’s something I learned from college athletics. As you can imagine, a lot of those courses were…
