Betty Kellenberger: Breaking Records at 80
Forget those cozy rocking chairs.
Last summer, at the age of 80, Betty Kellenberger set a remarkable milestone by becoming the oldest woman to complete the challenging 2,193-mile Appalachian Trail.
Kellenberger, who dedicated 41 years to teaching middle school in Carson City, Michigan, has long harbored a dream of hiking the expansive trail that stretches across 14 states, from Mount Springer in northern Georgia all the way to Mount Katahdin in central Maine. But, as she reflected, “life got in the way,” she shared.
After retiring in 2009 and enjoying eight years as a county commissioner, along with traveling, she realized it was time to seize the opportunity.
She recalled contemplating, “Should I wait until I hit 90?”
Her ambition was to be a “thru-hiker,” a term for those who tackle the rugged path within a year’s time. Though she aimed to finish it in one continuous stretch, obstacles cropped up, and she found herself restarting multiple times.
Kellenberger kicked off her first attempt from Springer Mountain in Georgia in 2022, heading north. There, she met Joe Cox, a Navy veteran, who became her hiking companion.
Roughly halfway through at Harpers Ferry, West Virginia, they decided to “flip” and flew to Maine to conquer Mt. Katahdin before winter arrived. Unfortunately, Joe faced a fall that sent him home, leaving Betty to continue alone, but her journey ended just three days later when she contracted Lyme disease.
The following year, she resumed from Harpers Ferry, making it to Massachusetts but then suffered a fall that required knee surgery.
During her recovery, Kellenberger diligently climbed hospital stairs to prepare for her next hike. In 2024, she set off from Harpers Ferry once more, this time heading south, dedicating her adventure to Joe, who had passed away.
Her adventures saw her reach Hurricane Helen before she was advised by the Appalachian Trail Conservancy to leave the trail, with a promise that returning in 2025 would still allow her to count the miles already covered.
In her fourth and final attempt in 2025, she began in Damascus, Virginia, making her way to Springer Mountain and then flying north to wrap up the trek.
Throughout her journey, she made a conscious effort to keep her backpack weight around 30 pounds, given her small stature.
“I’m petite, under 5 feet,” Kellenberger remarked. “We had minimal clothing—just sleeping bags and tents—and had to carry our food until reaching the next town.”
Along the way, she encountered “trail angels,” generous locals who provide hikers with water, homemade meals, snacks, and supplies.
On September 12, 2025, she finally reached her goal.
Upon her return, the community honored her with the naming of a hiking trail as the Kellenberger Trail.
The oldest person to hike the entire trail remains MJ “Nimblewill Nomad” Eberhart, who completed it at the age of 83 in 2021.
Now, Kellenberger offers insights for other older adults.
“The more you move, the better you feel,” she advised. “The more active you are, the more active you become.”
While Kellenberger revels in her accomplishments, she also wishes to clarify something.
“Everyone asks, ‘Did you see a bear?’” she noted. “The only bear I’ve ever seen was when the road passed through a zoo. I did spot a moose in Maine once, but it was a bit skittish and quickly wandered back into the woods.”
