Annadel Half Marathon/10K/5K
The Annadel Half Marathon is a non-profit fundraising event. Over the past 14 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 2025 event!
The Annadel Half Marathon, 10K, and 5K are considered to be one of the biggest running events in Sonoma County!
*The Half Marathon has a 4-hour cut-off time. The shorter courses are better suited for walkers. Sorry, no refunds or transfers.
