Darren Weldrick, founder of RUNWAY and RUNTOMTL, shared why supporting Noah’s mission is deeply personal to him:

“More than a decade ago, one of the first people I spoke to about RUNTOMTL was my close friend, Colin Buchanan, who later lost his life to brain cancer. I had the privilege of coaching and supporting Colin through two separate brain surgeries, and his courage continues to inspire me to this day. RUNTOMTL was born out of resilience, endurance a desire for adventure, and a Little Rock and Roll. But the inspiration to make it happen came from brain cancer taking away a dear friend too early. I feel for Noah, and I want to make this journey for him more meaningful in any way I can. And I’m really just appreciative of the opportunity and privilege to do that.

In Memory of Sejin Lee
On February 21, 2020, Sejin Lee, a devoted wife and loving mother of two, passed away after a courageous battle with Glioblastoma (GBM), one of the most common and aggressive types of cancerous brain tumours. She was just 40 years old.

Like so many taken too soon by this devastating disease, Sejin was unable to experience many of life’s milestones that parents cherish: watching her children graduate from university, pursue their dreams, and one day build families of their own.

Sadly, Sejin’s story is not unique. Every day, approximately 27 Canadians are diagnosed with a brain tumour – 9 of those diagnoses are cancerous. Behind each statistic is a person, a family, and a future forever changed. Across Canada, thousands of families each year face the devastating reality of a brain cancer diagnosis and, inevitably, the profound loss that follows.

For her son Noah, this run is both a tribute and a mission. “I’m running this for my mom. She fought this disease for nearly four years, treating every single day we had together as a blessing. When I reflect on her superhuman love, willpower, and perseverance, running this 70-kilometre distance pales in comparison. But this run is about more than honouring her memory. It’s about creating hope for future patients and families by helping to fund the research that will lead to better treatments, longer survival, and ultimately a cure. I want other families to have opportunities and outcomes that simply weren’t available to mine.”
