Donna Senty’s running journey started with a few miles here and there, but one unexpected turn changed everything.

Donna ran occasionally from 2015–2019 and even joined in when her kids were in high school, but running was never a major part of her life. Then, during a race in October 2024, a simple mistake turned into a life-changing moment. Donna accidentally turned right instead of left and ended up running a half marathon instead of a 10K.

That unexpected extra distance sparked a new goal: running all 50 states.

Since then, Donna has embraced every opportunity to explore the running world. A friend introduced her to trail running in 2026, opening the door to a whole new type of adventure. Timberline became her 16th state, and with Hawaii next on the list, her journey is far from over. She’s also taken on incredible challenges like the 30K at Antelope Canyon.

For Donna, running is about much more than race medals and finish lines. It’s her happy placeβ€”a way to stay physically and mentally strong while exploring new places and creating unforgettable memories.

What started as an accidental wrong turn became a path toward adventure, discovery, and a goal to run across all 50 states.

Welcome Laurie to Featured Runner Friday!

Laurie Allen found her inspiration in an unlikely placeβ€”her son, Tyler.

Although Tyler was a varsity athlete in high school, running wasn’t always his favorite activity. While playing baseball, he had a habit of hitting the ball hard and then taking his time around the bases, earning him the nickname β€œWheels” as his older brother cheered him on from the stands.

Years later, Tyler’s running journey took a different direction. He recently completed his 7th marathon, and his dedication inspired Laurie to ask how she could take on a marathon herself. His advice was simple: β€œOne mile at a time.”

At 60 years old, Laurie decided to take her first step into the running world by completing her first raceβ€”a 5K. Not only did she cross the finish line, but she also earned 3rd place πŸ₯‰ in her age group.

For Laurie, this race was about more than a result. It was about following inspiration, trying something new, and proving that it’s never too late to start your own running journey. With a little motivation from β€œWheels” and a commitment to take it one mile at a time, Laurie is just getting started.

Welcome our next Featured Runner ... Adam!! πŸŒŸβ€ΌοΈ

Running changed Adam's life in ways he never imagined.

In high school and college, Adam weighed over 300 pounds. Wanting to improve his health and with the hope of one day becoming a father, he decided it was time to make a change. What started as a commitment to get healthier gradually became a passion that transformed his life.

Today, Adam is the proud dad of two boys, and one of his greatest joys is knowing they get to watch him accomplish things he once thought were impossible. From crossing finish lines to taking on new running challenges, every mile is a reminder of how far he's come.

For Adam, running has always been about more than fitness. It's about setting an example, showing his sons that hard work, perseverance, and consistency can completely change the course of your life. The person who once struggled with his health is now inspiring the next generation through every race he runs.

His journey is proof that it's never too late to rewrite your story, and that the finish lines you never thought possible might just be the beginning of something even greater.
