Why Work with Us?
From I.T to Sports Scientist for National Athletes
Hi, I'm Shawn.​
I spent over a decade in I.T.—but my obsession with data and performance eventually pulled me into endurance sports.
​
Now, I help cyclists and triathletes train smarter, not harder—by turning lab data into clarity & confidence.
