Breaking Barriers
Kathrine Switzer became the first woman to officially run the Boston Marathon, despite officials trying to remove her mid-race.
Why Iron Fox Exists.
Iron Fox was born from experience. In June 2024, while training for the Midnight Sun Marathon in Tromsø, Norway, I began to feel the impact of my cycle in a way I could no longer ignore. My energy fluctuated and performance dropped.
My body stopped responding the way it should. I was later diagnosed with amenorrhea, a condition widely recognised in sports science and closely linked to Relative Energy Deficiency in Sport (RED-S).
After recovering and returning to training, I started looking at how I could better support my body through sports nutrition. I assumed there would already be products designed to support how women actually train, recover and perform. There wasn’t.
What I found instead was an industry where products have been designed around male physiology and formulated using male-focused research. So I built what didn’t exist.
IRON FOX.

Global Growth
Women’s sport has never been bigger. Yet only 6% of sports science research focuses exclusively on female athletes.
The future of female performance deserves better.
