The 2025 East Bay Dirt Classic is in the books! Thanks to all participants who made this year the best edition yet!

Between the record number of participants, beautiful weather and setting a new record of over $82,000 raised for the Alameda County Community Food Bank, it was our best edition yet. Thanks to all who raced and helped fundraise, we are able to help provide more than 164,000 meals for those Alameda County members who face food insecurity daily.

In the men’s division, 2024 winner, James Kinney, and 2024 runner-up, Sandy Floren, battled it out through the first 2/3rds of the course with Sandy eventually pulling away on Redtail. Sandy ultimately finished first with James in second and young gun, Nils Hummel, taking third

In the women’s division, Sophia Tripcevich returned to reclaim her title from 2024, followed by Sadie Weiner in second and Elle Floren in 3rd. Sophia also once again took home the prizes for top female junior AND QOM!
