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 three programs, which encourage students beginning in kindergarten through high school the opportunity participate.

Read, Right & Run Marathon®

The GO! St. Louis Read, Right, & Run Marathon® (RRRM) presented by Express Scripts was launched in 2001 and quickly gained national recognition, most recently recognized by RUNNING USA as the “2013 Youth Program of the Year.”The program’s goal is to develop reading-proficient, community-minded and physically fit children in grades K-5 by challenging them to READ 26 books, RIGHT the community with 26 good deeds, and RUN 26.2 miles over a six-month period. It is a standards-based, sustainable, enrichment program that endorses and supports existing school curriculum.

Middle School Milers

GO! St. Louis Middle School Milers was created in 2014 to meet the needs of students in grades 6 – 8, who are at an in-between period where fitness can have a big impact on not just their physical health, but their overall outlook. Many schools may not have a developed sports program but a running/walking enrichment program may provide an energy outlet for students. Students will follow a 9-week training program with a goal of running/walking the GO! St. Louis 5K on April 9, 2016.

Students on the GO!

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 or walk (or a combination of both!) 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.


If you are looking for a fun and rewarding experience, consider joining the more than 3,000 volunteers who help make GO! events and programs a success. The GO! St. Louis Marathon & Family Fitness Weekend requires the majority of our volunteer needs, but as a not-for-profit organization, we have additional events such as the All-American 5K & Fun Run, The Great GO! St. Louis Halloween Race and the GO! Missouri KT82 Trail Relay, which require additional volunteer support.  Learn more…


We are seeking sponsor partners who understand the importance of encouraging health and fitness as a way of life and providing people with an avenue to accomplish their personal goals.

Sponsoring a GO! St. Louis event or program means supporting goal-oriented people, reaching a diverse audience and distinguishing your products and services through positive exposure.
