At 80, when for many adventure is limited to a walk outside the house, Betty Kellenberger has rewritten a world record. The former teacher from Michigan has become the oldest woman to have completed the entire Appalachian Trail, the famous hiking route that crosses the United States from Georgia to Maine for approximately 3,540 km, passing through 14 states and thousands of meters of altitude difference.
A dream born at school
The idea of hiking the Appalachian Trail has been with Betty since childhood, when she first read about it in a Weekly Reader in elementary school. For decades, adult life, work and commitments have postponed that desire. Then, approaching eighty years old, the decisive question: how much time remains to postpone such a big dream? From there began methodical preparation and a series of attempts that would test even much younger hikers.
An obstacle course
The path was not linear. In 2022, a first start was cut short amid dehydration, Lyme disease and a concussion. The following year, another fall forced Betty to stop again. To complicate everything, knee replacement surgery and the loss of her hiking companion, Joe Cox, to whom Betty decided to dedicate the enterprise. Each stop, however, became part of a journey of learning and resistance.
The hurricane and the unexpected turning point
In 2024, while hiking a new route, Hurricane Helene made large sections of the trail impassable in the Southern United States. The authorities offered hikers an extraordinary solution: suspend the journey and resume it the following year without losing the kilometers already travelled. For Betty it was a forced but decisive break. In Michigan, where the terrain is flat, she trained by climbing stairs every day in the hospital to simulate the mountain differences in altitude.
In 2025, Betty returned to the trail to complete the last missing sections, tackling the toughest sections between New Hampshire and Maine, known for rocky terrain and challenging climbs. On September 12, when she reached the northern end of the trail, she surpassed her previous record of six years, officially becoming the oldest female thru-hiker on the Appalachian Trail. A result built step by step with a determination that allowed her to make history.
