High school track and field athletes - particularly distance runners - often get unfairly branded as one-trick ponies. The perception is that they're capable of doing one thing, and one thing only: running distances between 800 meters and a hair over three miles quickly. Sure, for some that's true.
For every fourth runner on a high school cross country team who's also the school's starting point guard, there are several who would look like a Vaudville performer slipping on a banana peel if asked to make contact with a moving soccer ball.
That doesn't mean distance runners - even those averse to other sports - are unathletic. Far from it! Running a mile as quickly as you possibly can requires a great deal of athletic ability. But generally speaking, becoming great in one endurance event requires a level of focus, dedication, and most crucially, specialization that makes being great at anything else challenging.
But there are of course exceptions to that rule, like Reese Vannerson.
Vannerson was a standout cross country and track athlete for Strake Jesuit in Houston, where he set still-standing school records in the 1600m and 3200m of 4:06.87 and 8:49.10, respectively. As a senior in, he was the 2023 UIL 6A champ in both events. 
But what his competitors and those who only knew him from his exploits in a Strake Jesuit jersey may not have known is that track and cross country were already not his primary sport, despite him being very, very good at them. Vannerson competed in his first triathlon when he was just eight years old, and has been all-in on the triathlon ever since.
This extremely detailed look at Vannerson's training as a youngster, courtesy of Coros, is fascinating and reveals a patient approach that has long favored bike and swim work, accompanying low mileage running-wise, even when running was the occasional priority. But it also points to an athlete who was more or less destined for the triathlon. As his high school running career was wrapping up, he made the call to forego signing with an NCAA program for track and cross country, and go all-in on becoming a pro triathlete. It wasn't a huge deviation from what he'd already been doing!
In his debut at the March 2022 Americas Triathlon Junior North Americas Championships Sarasota-Bradenton he placed fourth against top-tier junior athletes primarily from Canada, Mexico, and the U.S. After notching a DNF at his next tri, Vannerson got his redemption with his first registered junior-level triathlon victory at the Europe Triathlon Junior Cup Düsseldorf, where predictably his run was the best in the field--a 15:27 5k split after a grueling swim and run.
A month later, in Long Beach, California, he debuted against senior-level competition and held his own, placing eighth out of a 61-man field. In that race, despite his excellent running pedigree, he actually came close to matching his running performance on the bike, and didn't concede too much time on the swim.
And from there, the now-Arizona- and Colorado-based 21-year-old has continued to post impressive results various levels of competition. Across 41 starts in World Triathlon sanctioned events, he's finished atop the podium 18 times and notched nine wins.
Clearly, his early focus on running has been helpful to his success in the triathlon. At has most recent competition - the 2026 Americas Triathlon Championships Antofagasta - he closed out his race with a 30:00 10k split, the fastest in the field. But out of the 60+ athletes in the field, he still managed to record the 13th best swim and ninth best bike. Vannerson is hardly a runner who dabbles in the triathlon at this point - he's very much a triathlete who's still a phenomenal runner.
Each of the past three winters, he's given the running world a taste of what might have been had he stuck with a sole focus on the oval, venturing up to Boston University's venerated indoor track for a good old fashioned 5000m race against professional runners and high-end collegiate athletes. At these annual pilgrimages back to the sport that served as his triathlon springboard, he's run 14:08.40 (2024), 13:48.59 (2025), and 13:45.89 (2016).
Remember, that's without a true focus on running. These races are just benchmark efforts along his path to becoming the best-ranked triathlete in the world. He currently ranked #41 in the world, and fourth out of athletes also born in 2005, so he's got plenty of room to grow before his first shot at hunting an Olympic medal in 2028. And if anything, compared to other recent American triathlon greats, he's ahead of schedule just by already having competed at a high level in his teens.
Before Gwen Jorgensen won gold in Rio, she was a standout on the track and in the pool as a high schooler in Wisconsin, an then at the University of Wisconsin. Despite the fact that she graduated having never raced a bike before, based on her accomplishments in two-thirds of the triathlon's events, she was recruited by USA Triathlon as part of its College Recruitment Program.
More recent medalists Morgan Pearson and Katie Zaferes are also products of this system. But before earning Olympic medals, they were stars for the University of Colorado and Syracuse University cross country and track teams. Because they both had competitive swimming backgrounds, they drew the attention of USAT, and the rest is history.
Because the upfront barrier to entry for the triathlon is way higher than it is for track and field, there are undoubtedly plenty more runners who happen to be strong swimmers in this country who possess incredible potential in the triathlon. And while USAT is committed to tapping into that talent pool, for most athletes, it'll take hopping on a bike as well and entering a race at their own cost to find out what they're made of.
