The 13th annual Loop the Lagoon family fun run is Saturday in Lagoon Valley Park.
The event benefits the Vacaville Public Education Foundation, and partner Fleet Feet Sports in Vacaville said they are determined to make it the best Loop yet.
Event organizers promise family fun, food, music and more.
The event kicks off at 8:20 a.m. Saturday with the 5K run/walk loop around the lagoon.

Computerized timing and results will be in place for the 5K, 10K and Tower Challenge.
Prizes, provided by Brooks Sports, are three deep in each 10-year age category for these races.
