Sunday, October 17, 2021 • Elk Grove, CA • Course Map

Note: A virtual option is available for this event, to be run anytime from October 14 to October 31. Registration details are included below.

Runners and walkers will get the chance to trek the streets of this fast-growing Northern California city just south of Sacramento at the Kaiser Permanente Running of the Elk Half Marathon, 10K and Thrive 5K, which makes its 9th annual running this fall as a fundraiser to benefit the Youth Sports of Elk Grove Foundation.

The course for the race will follow an out-and-back route that starts and finishes at the Elk Grove Auto Mall, which lies on Laguna Grove Drive, just off the South Sacramento Freeway/Golden State Highway.

From there, runners will head out on a 13.1-mile route that takes them through this city that earned the title of the fastest-growing city in the United States back in the mid-2000’s, according to U.S. Census figures.

The race — which is also part of the California Half Marathon Series — has beeen limited to 1,500 to 2,000 entrants for the individual half marathon in the past, so prospective runners are encouraged to sign up early to ensure they receive a spot in the race.

The field limits will also be set to 2,000 entrants for the Thrive 5K race.

Runners in the half marathon and relay will be limited to a 4-hour course time limit, and 10K runners and walkers will have 2 hours, 20 minutes to complete the course. Participants running or walking the 5K race will have one hour, 2o minutes to complete their course.
