From the organizer

Join us for another year of fun in the sun! At the Jolly10k you'll take a 10K or a 5K run or walk, through stunning Los Gatos mountain trails and arrive back at the finish line to enjoy fun, food and fellowship. We have informational booths, a variety of resource tables, CPR training and as always the Los Gatos Fire Dept. joins us for a group photo with the Fire Engine. We definitely have fun, but the reason we gather for the Jolly10k is to create a safe environment to have the difficult conversations about addiction and the deadly epidemic of Fentanyl that has flooded our country and stolen far too many young lives. But together, we can remember our loved ones and share life-saving information on how to prevent the next life lost from being someone in your family.                       Excercise, Information & Education!
