The Annadel Half Marathon

The Annadel Half Marathon is a non-profit fundraising event. Over the past 9 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 10th annual event!

The Annadel Half Marathon and 5K is considered to be one of the biggest running events in Sonoma County!
