About the Lafayette Res Run for Education
The Lafayette Chamber and the City of Lafayette are co-sponsors of the Lafayette Res Run for Education which is traditionally held the third Sunday in October.
The 2025 Lafayette Res Run for Education will be held Sunday, October 19. 5k: 8am, 10k: 8:15am, 2 mile: 8:45am in downtown Lafayette, CA.
Back by popular demand, from its introduction in 2020, you can register for the Reservoir Challenge – the virtual race which “runs” around the 2.7-mile paved trail of the Lafayette Reservoir October 11-18. Please note, the Reservoir Challenge is not an option on Sunday, October 19 as the Reservoir will be closed for the 10K runners. The Reservoir Challenge is great opportunity to safely walk or run the Reservoir on your own, perhaps beating your time from last year.
Beneficiaries of the event are the local schools and the services and programs of the Chamber. See below for what we gave back to our schools last year!
The Run is the city’s most popular “family affair”, involving kids, parents, grandparents, and hundreds of serious runners from throughout the Bay Area. Join us in 2025 for the 10k, 5k, the 2 mile run/walk for fun or the Reservoir Challenge! Sprinters, walkers, the “stroller brigade” and many of Lafayette’s top four legged residents are welcome to join in the fun.
The first 100 students to register from each school will receive a voucher for a free 1/4 pound of bulk candy from Zoonie's during packet pickup!

Founders Running Club started in San Francisco in June 2022 when Tim, a startup founder, decided running and entrepreneurial culture should share the same ecosystem. What began as a small group quickly expanded into a thriving community of founders, investors, builders, creators, and curious minds united by the belief that great communities compound over time. Weekly runs launch from the William McKinley Monument, splitting into 5K and 10K groups that trace past Golden Gate Bridge views and through San Francisco's most storied neighborhoods. The crew operates on the same principles that build successful startups, openness and collaboration define the experience. No gatekeeping, no cliques, just people running together and building something meaningful at the intersection of movement and ambition.
Golden Gate Running Club has been gathering runners across San Francisco since 2001, creating a tight-knit community that celebrates fitness and friendship in equal measure. Founded on the belief that running with others, at any pace, is the whole point, the club welcomes everyone from marathon trainers to casual conversational joggers. With around 130 members strong, Golden Gate Running Club anchors its community through two weekly signature runs: Wednesdays at Kezar Stadium for track practice and Sundays starting at the Warming Hut on Crissy Field. From these iconic San Francisco locations to the city's most beautiful streets, the crew runs together, united by enthusiasm and a shared love of their city.
Unseen Run Club was founded by Justin in January 2023 with a simple observation: San Francisco's running scene didn't reflect the city's actual diversity. He built something different from the ground up. Running belongs to everyone, regardless of ethnicity, body type, or ability, and that principle sits at the foundation, not the margins. Around forty members now gather weekly, bringing different backgrounds, paces, and stories. The mix is the entire point. Conversations on the run go places that most social settings never reach. Every Tuesday at 6:15pm, the crew meets at Beulah Street and Stanyan Street for five to ten kilometre runs through Golden Gate Park and the streets surrounding it.
