The 33rd "Chestnut Run"

Registration for the 33rd "Chestnut Run" is Now Open!

On May 31, 2026, during Kyiv Day, the 33rd Annual Charity "Chestnut Run" will take place. This is Ukraine's first and largest charitable sporting event, which for over three decades has united people worldwide to help children with congenital heart defects.

In 2026, the event will be held in an online format for safety reasons, allowing participants from anywhere in Ukraine and across the globe to join. Participants can choose their own route, pace, and format (running or walking) while keeping the traditional 5 km distance. Organizers encourage not only individual participation but also the formation of teams and local starts in your home cities.

Last year, participants raised 2,000,000 UAH, which funded medical equipment for the Center for Pediatric Cardiology and Cardiac Surgery of the Ministry of Health of Ukraine. This year’s goal is to purchase a video laryngoscope, which allows surgeons to clearly see the airways of tiny patients during procedures, ensuring maximum precision and minimizing risks.
