Dozens of kids competed in a mini-marathon at Chuckchansi Park. The kids ran laps around the park. Some were just 2-years-old and had to walk, but all of them finished the race.
Organizers say this event encourages kids to stay healthy and active.
The Two Cities Marathon is set to start at 7:00 am.
There will be a lot of road closures around Fresno and Clovis.
You can also watch friends and family cross the finish line live on our Weather-Plus channel.
