My dear friend Claire Wouters was first diagnosed with non-Hodgkin lymphoma just over a year ago. She fought bravely and beat cancer once, but heartbreakingly it has returned, this time in her cerebrospinal fluid — a rare form affecting only about 50 people in the Netherlands each year.

To support Claire and others facing this battle, I’m running the Amsterdam Marathon on 19 October 2025 to raise both awareness and funds.

All donations will be shared equally: 50% will go to cancer research centres working on lymphoma and CAR-T cell therapy, and 50% will go directly to supporting Claire in her fight against cancer.

Every contribution, big or small, will make a difference. Let’s run this fight together for Claire.
