YOUTH FITNESS

GO! St. Louis is committed to fighting the rising rate of youth obesity and keeping St. Louis healthy and fit. Our unique youth programs have quickly gained national recognition and focus on developing physical fitness skills, nutrition tips, and training tools to encourage students of all ages to lead a healthy lifestyle. We offer two programs, which encourage students beginning in kindergarten through high school the opportunity participate.
The GO! St. Louis Read, Right, & Run Marathon® (RRRM) was launched in 2001 and quickly gained national recognition. The program’s goal is to develop reading-proficient, community-minded and physically fit children in grades K-8 by challenging them to READ 26 books, RIGHT the community with 26 good deeds, and RUN 26.2 miles over a 26 week period. It is a standards-based, sustainable, enrichment program that endorses and supports existing school curriculum.
Students on the GO! is a team-based program to engage high school students in an active and healthy lifestyle year-round. Students train to run the GO! St. Louis Half Marathon each April. Students embark on a personal journey of self-discovery where they explore and experience the lifelong benefits of a comprehensive health and fitness program.
