About the 5K and Fun Day for Fragile X
This is a charity walk-run that raises money for Fragile X syndrome research and awareness. The course offers a full loop and a shorter scenic option, so people cover different distances depending on what works for them. Bikes, scooters, and strollers are all welcome, and the pace varies widely across the field.
A family gathering follows the race, with food and time for families affected by Fragile X to connect with each other. Inspirational signs are placed along the course by sponsors recognizing participants. The event is organized by a Southern California nonprofit dedicated to the Fragile X community.
