Reggie's Run 2026

Boron, CA
5K Run/Walk (Run starting at 9am sharp. Please be there at least 30 minutes early to pick up bib) If you knew Reggie Heard, you knew that he loved his shoes and he loved the sports he played in them. Reggie also had a soft spot for younger kids and he often took the time to make each one feel special. The Boghosian family found a way to honor Reggie's memory by combining the things that he loved most and by creating a local nonprofit called REGGIE'S KICKS FOR KIDS. This program works to provide athletic shoes for boys and girls, of all ages, that share Reggie's passion for sports. The program will raise funds to provide athletic shoes for youth and will be working with local sports teams and leagues to ensure kids have what they need to play their respective sports. With the funds raised through the runs of past years, Reggie's Kicks for Kids has purchased hundreds of shoes for kids. Hope to see you again this year!
