At this year’s Boston Marathon, we had some impressive Fluid Runner finishes!
But the bigger story wasn’t just about speed. It was about resilience, adaptation, and a different way of approaching marathon training.
And even if you’re not a runner, don’t tune this out—the same principles apply whether your goal is staying active, building strength, or simply feeling better in your body.
Among the thousands of runners on the course were four Fluid Running athletes whose paths to Boston looked very different — in age, background, goals, and physical challenges — yet all shared one thing in common:
They used Fluid Running as a big part of their marathon training.
And the results were remarkable.
Doug Ginsberg (27) — 2:44 PR
Doug, a former American Ninja Warrior athlete known as the “Dyslexic Ninja,” has built his training around a hybrid approach of Fluid Running and land running, and specifically doing his speedwork in the pool!
Rather than relying solely on high-impact mileage, Doug uses Fluid Running workouts to build cardiovascular fitness, speed, and strength while minimizing the breakdown that often comes with marathon training.
The result? A personal best of 2:44 at Boston — and a body that remains healthy, durable, and capable of sustaining high-level training.
Jen Govostis (55) — 3:29 PR
At 55, Jen continues to get faster.
Despite being somewhat injury-prone, she has learned how to train smarter. She does about 50% of her runs in the water, and always her speed workout!
By replacing a substantial portion of her land running with Fluid Running workouts, Jen has been able to maintain consistency, recover more effectively, and continue setting personal records into her 50s.
Her 3:29 PR at Boston is proof that performance does not have to decline on a fixed timeline.
Dian Ginsberg (61) — 4:03
Dr. Dian Ginsberg is a lifelong athlete, multi-time Boston Marathon qualifier, Ironman triathlete, martial artist, and black belt who understands both the rewards — and the physical toll — of endurance training.
After battling overuse injuries, Dian began incorporating Fluid Running into her training to maintain running fitness while reducing impact and improving recovery.
At 61, she ran a strong 4:03 Boston Marathon — proof that endurance performance and longevity can coexist when athletes train intelligently.
Dian is also board-certified in both Obstetrics & Gynecology and Anti-Aging & Regenerative Medicine and is the founder of PrecisionFemCare, where she helps women optimize health, performance, and longevity through every stage of life.
Therese Kerman (64) — 5:40
For Therese, simply getting to the Boston starting line was meaningful.
As a runner managing arthritis in her knees, traditional marathon training can be especially difficult. Rather than giving up on the goal, she adapted her training by incorporating Fluid Running.
Those pool sessions allowed her to maintain fitness while reducing stress on her joints and managing the wear-and-tear that often accompanies marathon preparation.
At 64 years old, Therese crossed the Boston Marathon finish line in 5:40 — a powerful reminder that endurance sports can remain accessible, fulfilling, and possible even in the face of physical limitations.
How Fluid Running Helped These Athletes Train Differently
While each athlete’s journey was unique, all four relied on Fluid Running workouts to reduce the physical stress of marathon training while continuing to build endurance, strength, and cardiovascular fitness.
Through guided deep water running workouts, they were able to maintain high-quality training without constantly absorbing the pounding that often leads to fatigue, overuse injuries, and setbacks.
For Doug, Fluid Running became a way to train aggressively while staying healthy enough to sustain elite-level performance.
For Jen, the pool provided a way to keep training through injuries instead of repeatedly losing fitness every time something flared up.
For Dian, Fluid Running has allowed her to continue to both enjoy and excel in endurance sports into her 60s. She’s not stopping any time soon!
And for Therese, the workouts allowed her to continue pursuing marathon goals despite arthritis in her knees.
The combination of expert coaching, structured interval training, resistance-based conditioning, and zero-impact movement helped each athlete stay consistent throughout marathon preparation.
And in endurance training, consistency is often what changes everything.
The Bigger Story
These Boston athletes represent something larger happening in endurance sports.
The future of performance may not belong to the athletes who can simply tolerate the most impact.
It may belong to the athletes who recover intelligently, adapt creatively, and train sustainably enough to stay healthy for the long run.
Boston didn’t just showcase impressive times this year.
It showcased a different model for endurance training — one built on resilience, consistency, and longevity.
