KIDS RUN FREE
In celebration of its 50th year, Grandma’s Marathon has announced that it will offer FREE KIDS ENTRIES (18 & under) to each of the five Young Athletes Foundation races in 2026.
Healthy communities start with healthy kids. By removing the element of cost for these races, we hope to open the door for more kids to run, play, and discover what they’re capable of.
This is how healthy lifestyles start, and it’s just one of the ways we can help take care of our community and extend the amazing impact of Grandma’s Marathon past one weekend in June.
We hope there’s plenty of new faces at our events in 2026. We’re excited to see you at the start line!
