FUNXION was born high on the rugged trails and ridges of the Ko'olau Mountains, for those with an insatiable hunger for life and movement in all its forms.
I wasn't always an athlete, running found me when I needed it most, right before the birth of my 2nd daughter. 11 years ago, I hit the road and trails in search of work-life balance, not knowing it would ignite something deeper. After my first half marathon, I was hooked. A year later, I conquered my first 50k trail race, and from there the distances only grew. 50 mile races turned into 100 mile ambitions and soon I found myself at the start line of the legendary HURT 100 on Oahu. Battling unforgiving terrain, exhaustion and self-doubt, I crossed the finish line after 33 hours. Running had become my proving ground.
FUNXION is a rebellion against comfort culture, a secret weapon in your arsenal against the easy and the ordinary. ”
For years, I thought that running was all I needed, but in 2022 after tragically losing my mother far too soon, I made a commitment to do everything in my power to extend the length and quality of my life. That promise let me to strength training. I realized my thin runner's physique needed more muscle for the long haul. Longevity became my focus. As my training load grew with strength and run sessions, I knew my nutrition had to evolve too. I started hitting protein goals, and turned to evidence-based supplements to give me every edge. But what I needed wasn't out there--so I created FUNXION.
FUNXION exists to give athletes of all kinds, access to premium, yet simple, evidence based products. No nonsense, just stuff that works and compliments all your hard work. Our journey begins with FIRESTARTER.
