Betty Kellenberger, an 80 year old retired schoolteacher from Carson City, Michigan, became the oldest female to finish the Appalachian Trail after overcoming dehydration, Lyme disease, a concussion, a bad fall, knee replacement surgery, and Hurricane Helene across three separate attempts starting in 2022. Betty first learned about the 2,200 mile trail through 14 states in elementary school from a Weekly Reader and immediately thought she wanted to hike it someday, but adult life and her work as a teacher obstructed her path for decades until she finally asked herself how long she was going to think about it. Her first attempt in 2022 ended when her trail partner Joe Cox had a rough fall on Mount Katahdin in Maine and had to exit the trail, with Betty leaving several days later due to lingering health issues, while her second attempt in 2023 made it all the way to Massachusetts before a bad fall forced her to abandon the adventure. After knee replacement surgery and learning the sad news that Cox had passed away, Betty became determined to finish the trail in his honor, though Hurricane Helene in September 2024 toppled trees and made the trail so impassable that officials offered hikers an extraordinary deal to count their existing mileage on day one next year.
Betty trained by climbing steps every day at the local hospital because her Michigan surroundings were so flat, and when she headed out again in March 2025, she only had the northern and southern routes remaining since she had hiked between Massachusetts and Virginia before the hurricane hit. On September 12, Betty completed the northern end at age 80, besting the previous record by six full years and beating the 75% failure rate that claims most through hikers every year on a trail with collective elevation gain equivalent to hiking Mount Everest 16 times. Betty now shares a powerful lesson with everyone: get out, move, set a goal and work toward it, because the bigger the goal the greater the reward, and don’t let society or friends and family set your limitations since you might be surprised how far you can go once you simply take the first step.
