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!

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The 10K is the distance where running stops feeling like a starting point and starts feeling like a sport. Long enough to require a real training block. Short enough that race day is fully manageable for a first-timer who's put in the work.
Race day energy at a 10K is community at its best — strangers cheering you by name, people moving toward the same goal, an atmosphere that solo training can't replicate. It's fast enough that you'll spend the whole race pushing rather than managing your effort.
This is also the distance that builds the base for everything else. Most athletes who go on to run half marathons, do triathlons, or compete in HYROX started here. What you need: running shoes fitted to your stride, a training plan, and the race on your calendar. The registration is what makes the deadline real.
How long to train: 4–8 weeks for most fitness levels.
Running
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
