This cherished 5K run/walk, hosted at the expansive Frank G. Bonelli Regional Park, is more than just a race; it's a vibrant community gathering dedicated to raising awareness and funds for Fragile X syndrome, the leading inherited cause of intellectual disability and a significant contributor to autism. Participants are encouraged to run, walk, bike, scoot, or stroll, making it a perfectly inclusive and family-friendly event where superhero costumes are an optional, festive touch.

The course at Frank G. Bonelli Regional Park offers a welcoming environment for all abilities, designed to be accessible for families and individuals. Check-in kicks off at 9:00 AM, with the walk/run commencing at 10:30 AM, setting the stage for a day of movement and connection. Typical race day conditions in mid-April in San Dimas feature pleasant highs around 77°F and lows around 52°F, with a minimal 3% chance of precipitation, though organizers suggest being prepared for varying Southern California weather. Beyond the finish line, the celebration continues with a lively Family Fun Day from 11:00 AM to 2:00 PM, featuring free food like pizza, chips, cookies, and water, along with entertainment such as superhero characters, face painting, and a DJ. This event provides a "judgement free" space for families affected by Fragile X syndrome or any disability to connect and share.

The 5K for Fragile X is a cornerstone event for the Fragile X Association of Southern California (FRAXSOCAL), fostering public awareness, supporting scientific research, and building a stronger community for those impacted by Fragile X syndrome.
