Holiday Half Marathon & 5K

Sunday, December 15, 2024 • Pomona, CA • Course Map

The winter of 2009 brought a brand-new half marathon event to the Los Angeles County area here in Southern California, as the site of the annual L.A. County Fair played host to the inaugural running of the L.A. County Half Marathon at Fairplex, which also included a half-marathon for inline skaters and a 5K for runners and walkers.

Today, the race’s name has changed as it has become known as the Holiday Half Marathon, and its 2024 race will be its 17th annual running, Like in previous years, the race course is USATF-certified and the course time limit for those running in the half marathon is 3 hours, 45 minutes.

From the starting line inside the Fairplex, which lies about 30 miles east of downtown Los Angeles, runners in the half will follow an out-and-back loop course that takes them in roughly a counter-clockwise direction out from the fairgrounds and around the shoreline of Puddingstone Reservoir, through Frank G. Bonelli Regional Park and past the planes landing and taking off at nearby Brackett Field airport.

Hilly and challenging in some spots, particularly in the middle stretch of the race from mile 5 through 7, the course for the race takes runners through a combination of residential neighborhoods, past the tree-lined fairways of Mountain Meadows Golf Course and through more industrial-looking areas as the race nears the finish line along the eastern edges of the Fairplex fairgrounds.
