I’m running for a bigger life,  and against cancer

I’m running the TCS Amsterdam Half Marathon 2026 in support of the Dutch Cancer Society (KWF), but for me, this run represents something even bigger.

Our bodies were never meant to be something we spend our whole lives fighting. They’re the thing that carry us through every challenge.

They let us run, explore, work, travel, hug the people we love, experience adventure and say yes to a life that is so much bigger than how we look.

Cancer has a way of putting that into perspective.

So I’m taking on this marathon to raise money for KWF, to support people living with and beyond cancer, and to celebrate what our bodies allow us to do while we have the privilege of using them.

This is Be Well in motion, less body obsession, more LIFE.

Every donation, big or small, means so much.

Together we can make a difference. Against cancer. For life.
