Ironman finish line mindset Brittany Vermeer Run Tri Bike Running Tales

When Brittany Vermeer traded her equestrian saddle for a pair of running shoes, she didn’t just start a new sport. What happened was that she launched a whole new way of life. A ten-time world champion equestrian, Brittany transitioned into the world of endurance sports in 2019, beginning with humble “mailbox to mailbox” runs. Since then, she has crossed the finish line of seven half Ironmans and two full Ironmans, proving that it’s never too late to rewrite your athletic story or work on your mindset.

Mental Strength Over Metrics

Brittany’s story goes beyond finish lines. She opens up about the mindset needed to succeed in endurance sports, especially for everyday athletes balancing training with work and life. She talks candidly about overcoming imposter syndrome and the harmful trap of social media comparisons. Her choice to leave platforms like Strava and not post pace stats is rooted in a deeper belief: real growth comes from self-awareness, not social validation.

Instead of chasing perfection, Brittany journals her training wins in a “confidence book”—a tool she returns to before races. It’s a reminder that the strongest athletes don’t just train their bodies—they train their minds too.

Training with Support and Purpose

Brittany credits much of her progress to the support of her coach and her husband. Despite having different strenghts, Brittany is able to train with him for her events and his first Ironman. Together, they follow a “three-week rule” after races before choosing the next one, helping prevent burnout and honor recovery. She also leverages her journalism career to learn from elite athletes, using their stories to refine her own training approach.

Her current goals? Strengthen her run off the bike and master the art of patience—trusting that progress, especially in swimming, comes with consistency and time.

Real Talk About the Tri Life

Through her blog Triple Threat Life, Brittany serves up practical advice and encouragement from the lens of someone still on the journey. Her race experiences are honest and raw—like getting stung by a wasp mid-race or managing nutrition failures at Ironman Arizona. These stories don’t just highlight her grit—they offer reassurance that setbacks are part of the process.

And when pro triathletes like Emma Pallant-Brown and Haley Chura talk openly with her about self-doubt and mindset shifts, Brittany passes those insights on. This is an opportunity for the everyday athlete to be reminded that even the best struggle and still succeed.

Running Strong With the Right Mindset

What makes Brittany’s tale so impactful is her refusal to sugarcoat the work. She champions “doing the boring stuff”—those daily, unglamorous training sessions—as the foundation of success. Her message is clear: speed and podiums don’t define endurance athletes. Showing up, staying grounded, and embracing the long game does as crossing the finish line of an Ironman is a combination of physical preparedness and a strong mindset.
