Chula Vista Fun Run is a multi-use trail network at 2800 Olympic Parkway in the Otay Ranch area, serving hikers and runners with terrain ranging from gentle beginner grades to elevation-gaining intermediate routes. The trail system connects to the broader preserved-land network near Lower Otay Reservoir, placing it within the same southeastern Chula Vista recreation zone as Mountain Hawk Park on Lake Crest Drive. Panoramic views from the upper trail segments span Otay Ranch's residential ridgelines and the surrounding South Bay foothills, providing orientation landmarks that keep runners on-route without GPS. The Olympic Parkway trailhead offers parking adjacent to the Chula Vista BMX facility, and the 91915 ZIP code location places it within one of Chula Vista's fastest-growing residential corridors. Trail users training for organized 5K and 10K events also supplement mileage with the speed and agility programming at GreenSpeed Training Facility in eastern Chula Vista. The primary loop covers approximately 2.5 miles of packed-earth and decomposed-granite surface with a net elevation gain of 180 feet, incorporating switchbacks through coastal sage scrub habitat before descending to the Olympic Parkway staging area.
