The Annadel Half Marathon is a non-profit fundraising event to help build and maintain the trails in Annadel State Park. Over the past 7 years we have raised funds to make the park a more beautiful place for all to enjoy! Thankfully with the help of our sponsors, race participants, and volunteers this is a very successful event. We are looking forward to our 8th annual event!
The Annadel Half Marathon and 5K is considered to be one of the biggest running events in Sonoma County!
We are partnering with Underfoot Runs to offer the Annadel 5K. Funds raised through the Annadel 5K race will help to build new trails at Taylor Mountain Regional Park.
