I would like to welcome you to the 2026 Youth & Junior Nationals hosted at Voice of America Park in West Chester, Ohio. Youth & Juniors from around the country will battle head-to-head for National Championship bragging rights, and our goal is to create a memorable experience for all involved.

The calm waters of Voice of America Park should provide some fast swim splits. The Age-Group, Draft Legal & Mixed Relay bike and run courses were designed to be fast paced and spectator friendly. All races will finish in the heart of Voice of America Park, and “spirit central” where Team Zones will be located.

Special thanks to West Chester Ohio, Voice of America Park and Travel Butler County for hosting this exciting event. We are thrilled to return to this awesome location. I would also like to recognize Metro Parks, West Chester Township and the West Chester Police Dept. for their support. In addition, I would like to thank in advance the volunteers who will give of their time to make your experience a better one. While at the venue, please take the opportunity to thank these generous folks.

Enjoy your time in West Chester Ohio, represent your teams with pride and race to your fullest potential.
