#SmileLikeKay Across America – Virtual 5K Walk

Join us for #SmileLikeKay Across America, a virtual 5K walk happening on October 25th at 10:00 AM (EST)— live on TikTok! This special event is not just a walk; it’s a movement to raise awareness for Metachromatic Leukodystrophy (MLD) and to bring hope, joy, and meaningful support to families affected by this rare disease.

Participants from across the country are invited to walk, jog, or roll in their neighborhoods while we walk together virtually. Create a team, gather your friends and family, and fundraise to help us:

  • Deliver more Smile Like Kay Boxes to children at Duke Children’s Hospital
  • Donate a custom adaptive bike to a child who needs it — a gift that is often denied by insurance, yet provides immeasurable joy and health benefits

 About Smile Like Kay

Smile Like Kay is an initiative dedicated to honoring the joyful spirit and legacy of Kay, a brightly smiling little girl who courageously battled Metachromatic Leukodystrophy (MLD) — a rare, progressive, and devastating genetic disorder. Our mission is to bring comfort, joy, and a sense of normalcy to children enduring long-term stays in the pediatric bone marrow unit at Duke Children’s Hospital.

Through the Smile Like Kay Boxes, we deliver carefully curated care packages filled with activities, comforting items, and a whole lot of love. These boxes are designed to lift spirits during difficult treatments and remind children and families that they’re not alone. We also work to raise funds for essential adaptive equipment — such as adaptive bikes — that insurance often doesn’t cover but that provide children with joy, mobility, and therapeutic benefits.

At Smile Like Kay, we believe every child deserves a reason to smile, no matter their diagnosis.

Want to Donate?

You can donate directly using the link below. All donations go towards getting a custom adaptive bike to a child who needs it!
