On a bicycle fueled by “burger power” and boundless energy unleashed decades ago after giving up a four-pack-a-day cigarette habit, Jim Hoover, 75, recently completed the 3,000-mile journey of a lifetime: He walked, ran and rode a bike across America in 60 days starting at Tybee Island, Ga., and ending at the Santa Monica Pier in California.

“I had a friend who walked from South America to our college, but it took him two-and-a-half years. I knew I couldn’t do that, so I came up with a plan and bought a bike about a year ago,” said Hoover.
