MARCH 19, 2026 – The sound of pounding feet on asphalt synchronized to Air Force Senior Master Sgt. Tiffany Hallmark’s heartbeat as she crossed the mile 20 mark. Doused in sweat, stomach involuntarily empty since mile 7, Hallmark anguished through the final 6.2 miles toward the finish line. In her 18th marathon, she knew the feeling of triumph would follow this pain.
“At some point in every one of those races I’ve wanted to walk off the course,” she explained. “And I can tell you there have been many points in my military career when it’d been like that … but it’s about being able to persevere through those hard things while also concentrating on what you’re in right now.”
This mental resilience has been crucial during her diverse Air Force career. She credited her success to mindfulness and treating professional challenges like miles in a race.
“When you’re running, it’s about concentrating on the mile you’re running right now,” Hallmark said. “I know I have 20 miles left, but I am only going to think about mile 6. And so, in the military, I’ve really tried to do that.”
That focus is the bedrock of a grueling training regimen that precedes every race. Preparing for a marathon is a monthslong commitment involving more than just long-distance runs.
Hallmark’s typical training week consists of speed workouts, tempo runs to build endurance, recovery days, cross-training and one progressively longer run that can last for hours — all supported by a strict focus on nutrition and hydration. Her daily running habit evolved into a more balanced and sustainable approach to fitness.
“Before I had my kids, I was running 80-90 miles a week and the amount of food you have to eat for that is ridiculous,” she confessed. “Even though I was eating what most people would consider, for my weight and size, an insane amount of food … it was not enough.”
Running has always been a constant in Hallmark’s life, something she can rely on. But finding the balance of fitness that works for her body, mind and busy schedule was a challenge. Now, she compares her running routine to being as normal as having a morning coffee.
“Now that I have a coach helping me, I am running 55 miles a week,” she said. “My weight maintains, and I feel strong on my runs.”
That philosophy of finding a balanced, effective approach extended directly to her work. As the chief of cyber operations for the 446th Force Support Squadron at Joint Base Lewis-McChord, Washington, her leadership focuses on her people. Air Force Senior Master Sgt. Dwyane Williams, her noncommissioned officer in charge, praised her mentorship.
“Hallmark exemplifies the Air Force core values, and she motivates us in more than just fitness,” Williams said. “She is a great asset to the team.”
Her holistic approach to readiness embodies a recent shift in the service. The Air Force introduced new standards and scoring models to its Physical Fitness Readiness Program. This new program is designed to better prepare airmen for modern challenges and to help them stay healthy for their entire careers.
For Hallmark, this focus on the whole person has always been her primary mission.
“We are all giving something to the military, but I want to help my people become the best version of themselves too,” she explained. “I am passionate about that, about taking care of people — that’s what I want to do every day.”
In the end, Hallmark said every finish line crossed serves as a powerful reminder. That feeling of hard-won triumph as she crossed the finish line of that 18th marathon is what she strives to replicate in her squadron. By showing her people how to endure the race with a steady pace, she ensures they are not only fit to fight, but ready to finish strong, delivering the resilient and combat-ready airmen the Air Force needs to succeed.
