For Dr. Adrian Ionescu, a cardiothoracic anesthesiologist and biotech safety expert, life is often defined by high-stakes challenges. By day, he ensures the safe clinical development of investigational molecules spanning from pre-clinical animal trials to first-in-human studies. But outside the lab, his challenges are measured in miles, taking him across the globe in pursuit of the world’s most prestigious marathon finish lines.
“When I don’t run clinical trials, I just run,” he jokes.
Born in Bucharest, Romania, Adrian’s life has been characterized by movement, with the long miles always being at the epicenter. His journey took him through Vancouver, British Columbia, high school and medical school in Pennsylvania (where he met his wife, also a physician), and anesthesia training at Georgetown University and Harvard School of Medicine. After serving as faculty at the Massachusetts General Hospital in Boston, he eventually landed in the coastal town of Encinitas, California. But no matter the zip code, running has remained a constant.
The “Why” Behind the Miles
Adrian has been a marathoner for a long time, but his decision to run with Team IMPACT Melanoma is deeply personal. A friend and coworker—also an avid runner—was recently diagnosed by melanoma. Her battle struck a chord, driving home the reality that even the healthiest, most active individuals are vulnerable without proper sun protection.
When his friend introduced him to IMPACT Melanoma, Adrian knew he had found his cause. He has already run the Berlin and New York City marathons with the team, and this year, he is adding Los Angeles and Boston to his roster in honor of his colleague.
“I know from my day job that prevention is the best solution, and IMPACT embodies that,” Adrian explains. “Melanoma is preventable with safe sun habits, and that comes from education. IMPACT Melanoma does that better than anyone.”
A Global Pursuit with a Boston Strong Heart
Adrian is a student of the sport, currently chasing the Abbott World Marathon Majors. With Boston, Berlin, Chicago, and New York under his belt, he is tackling Tokyo on March 1st and Los Angeles on March 8th. But he isn’t stopping at the traditional six. With the recent expansion of the Majors, Adrian has his sights set on Sydney, Cape Town, and Shanghai to complete the grueling nine-star circuit. Beyond the Abbott World Marathons Majors Circuit, Adrian is also taking dead aim at qualifying for the 2028 Team USA Men’s Marathon Olympic Trials, a reminder of a perennial Avicii chorus line, “…one day you’ll leave this world behind, so live a life you will remember.”
Yet, despite his global itinerary and Olympic ambitions, one city holds his heart: Boston. During his time living in the city, he would often walk down to Boylston Street just to watch the marathoners cross the finish line and soak in the palpable energy of Patriots’ Day. Now, returning as a runner, he understands exactly why it is the center of the marathoning world.
“Boston is, for me, the most special race I’ll ever do,” Adrian says. The marathon distance is always the same, but he notes that the final stretch in Boston is entirely unique. “The last five or six miles, the energy of the city literally carries you across the finish line. You connect with strangers in a way I haven’t experienced anywhere else. Even with 30,000 runners in the marathon field, the crowd calls out your name. It feels like the brightest spotlights are on you.”
Superstition in the Arena
Marathons are as much mental as they are physical, and Adrian doesn’t leave the starting line without his signature armor: a red headband and red shorts.
Red is his six-year-old son’s favorite color, but it serves a dual purpose on race day.
“You know a marathon is always going to be tough and test you both physically and mentally no matter how much you’ve trained, so it feels like you’re entering an arena,” Adrian says. “That red feels powerful and action-ready. It makes me feel like the bull in the arena.”
Passing the Baton
That grit is exactly what Adrian hopes to model for his three young children. The message is already sinking in; his oldest son recently ran a school Jog-a-thon, sprinting the equivalent of a 10K just to be like his dad—and still went to soccer practice afterward.
For Adrian, the lesson goes far beyond the track. He wants his kids to understand that when you have a massive goal, you need to have vision and push through the temporary discomfort to win the little victories along the way. One step, one mile, one day, one week… and before you know it, you’re through, you’re having an IMPACT.
The Battle Cry
As he prepares to take on Tokyo and Boston in 2026, Adrian feels incredibly privileged to raise funds and awareness for a cause that saves many lives through early education. He leaves us with a rallying cry for both runners and supporters alike:
“In marathons and life, every step counts… make every stride have IMPACT.”
