At 6:03 a.m. on a Tuesday in March, Harold Nakamura steps off his front porch on Mattie Street, zips his windbreaker to the chin, and begins walking. He doesn't check the weather first. He doesn't stretch. He just goes — left on Mattie, right on Mueller Boulevard, past the closed coffee shops and the quiet playground, toward the Lake Park trail that loops around the retention pond and back.

He has done this every morning for nine years. He is 92 years old.

"People ask me what my secret is," Harold says later, sitting on his porch with a cup of green tea, barely winded from the two-mile loop. "I tell them: I don't have a secret. I just walk. If you walk every day, you don't need a secret."

The Route

Harold's route is exactly 2.1 miles — he measured it once with a pedometer his granddaughter gave him, then never used the pedometer again. He knows the distance by feel: the gentle rise near the Thinkery, the shaded stretch along the east side of the lake, the spot where the redwing blackbirds nest in spring.

He knows the other morning regulars, too. The woman with the two corgis. The runner in the green shoes who always waves. The man who does tai chi near the amphitheater. They don't talk much. A nod, a wave. The fellowship of people who are awake before the neighborhood.

Before Mueller

Harold moved to Mueller in 2017, at 83. Before that, he'd lived in the same house in South Austin for 41 years — the house where he and his late wife Midori raised three children, where she tended a garden that won neighborhood-association awards, where she died of pancreatic cancer in 2016.

"After Midori, the house was too big and too quiet," Harold says. "My daughter found this place. She said, 'Dad, there are trails.' I said, 'I'm 83, I don't need trails.' She said, 'You will.'"

She was right. The first morning walk was a half-mile shuffle that left him winded. Within a month, he was doing the full lake loop. Within a year, he was doing it in under 40 minutes. Now, at 92, it takes him about 45 minutes, and he doesn't care.

What He Sees

Nine years of morning walks have made Harold an inadvertent chronicler of Mueller's changes. He watched the Aldrich Street retail corridor fill in, storefront by storefront. He watched the lake park's trees grow from saplings to canopy. He watched families move in, have babies, push strollers along the same path.

"I've seen this neighborhood grow up," he says. "It's like watching a garden. You don't see it change day to day. But you look back and everything is different."

Harold's three children — a doctor in Seattle, a teacher in Houston, and a lawyer in Austin — worry about him living alone at 92. He tells them the same thing every time: "I walk two miles every morning. When I can't do that, we'll talk."

Tomorrow morning at 6:03, he'll zip the windbreaker and go.
