Join thousands of San Diegans at Balboa Park on Saturday, October 18, 2025 for Walk4ALZ, the region’s largest annual fundraiser for Alzheimer’s care and research, hosted by Alzheimer’s San Diego. The 2.75-mile walk begins at 8 a.m. (festival area opens at 6:30 a.m., opening ceremony at 7:45 a.m.) and raises critical funds to support the 100,000 local people living with dementia and their caregivers.

Registration is free, and every dollar raised stays in San Diego County to provide support groups, caregiver resources, educational classes, and research funding. Participants can register individually or as part of a team, and anyone outside San Diego can also join virtually by walking “anytime, anywhere” that weekend.
