Scientists sometimes undergo marathon lab sessions late at night as they race to explain the world's unsolved mysteries.
Research technician Jesse Lang takes such endurance to new levels when he spends his free time running 100-mile races.
Lang's day job at the Department of Energy's Pacific Northwest National Laboratory involves exploring how nuclear waste can be turned into glass for safe, long-term storage.
But his extracurricular habit recently led him to finish 20th in the Western States 100-Mile Endurance Run, which was held June 24-25 in California. He completed the grueling trail run in 20 hours, 9 minutes and 50 seconds despite the temperature peaking at 100 degrees.
The two tasks are related, Lang says.
"Both research and running help me to think I can accomplish or finish things I set my mind to, and that I can clear hurdles through determination."
The Tri-City Herald recently published a feature story that detailed Lang's passion for running.
"You run a lot of miles, and then you run some more miles," Lang told the Herald. "This year, it was the most miles I've ever ran. By May, I was averaging over 100 miles a week."
Lang started running exceptionally long races in 2011, has placed first 11 times, and finished in all but two of the 38 races he's started, the Herald reported.
Lang joined PNNL in 2009. He holds a bachelor's degree in chemistry from Central Washington University and is pursuing a master's degree in environmental science at Washington State University's Tri-Cities campus.
