This Saturday, March 21, 2026, runners of all levels will converge on Brisbane, California for the highly anticipated 9th edition of the Marina Double 15K. Now a celebrated tradition at this scenic location, the event has earned a reputation for its fast, flat course and family-friendly atmosphere.

Participants can choose from a variety of distances: 10K, 5K, the challenging Double 15K, or the Kids’ Mile (for runners aged 13 and under). Each course provides an opportunity to push your limits while enjoying the stunning Bay Area scenery.

All entrants will receive an official race shirt and tote bag, and every finisher will take home a well-earned medal. Age-group winners across all events will earn a special performance medal, and trophies will be awarded for each of the three races. Top performers in the Double 15K will also be eligible for $200 in cash prizes ($100 for the first-place man and $100 for the first-place woman).

Conveniently located just 20 minutes from downtown San Francisco, one hour from San Jose, and only 8 minutes north of the San Francisco International Airport, Brisbane provides an ideal backdrop for a race day filled with refreshments, food, and lively event atmosphere.

From first-time runners to seasoned athletes, the 9th edition of the Marina Double 15K promises an unforgettable experience—a day to hit the road, push your limits, and soak in the breathtaking beauty of the San Francisco Bay.

Runners gathered at the scenic Brisbane, California Marina March 22 for the annual Marina Double 15K, a one-of-a-kind event featuring a two-stage race: a 10K followed by a 5K, with combined times determining the overall results. In true Double Racing fashion, the 5K starts exactly 1 hour and 45 minutes after the start of the 10K, putting athletes to the test both physically and mentally.

The Marina Double 15K is an official event of the Double Road Race Federation (DRRF), the governing body of the sport of Double Racing. The sport was created by Bob Anderson, founder of Runner’s World magazine. The first official Double race was held in Mexico in 2010, and the format has since grown internationally.

In this unique format, the top honor—the Double Victory Cup—is awarded to the runner with the best age-graded score over the full 15K. This year, 19-year-old Jackie Holman earned the top distinction with an age-graded score of 83.48%. She ran the 10K in 37:49 and the 5K in 17:46, giving her a combined time of 55:35 and the overall win.  This shattered the best time ever for females 19 and under.  The previous record was 57:22 set Dec 22, 2013 in Pleasanton, ca by 19 year old Natalie Dimits.  

Anthony Cortes posted the fastest overall time of the day with a 33:23 in the 10K and a 16:46 in the 5K, totaling 50:09. His age-graded score was 82.12%.

In the 10K Open, Andrew Elder (age 31) finished first among the men with a time of 36:46, and Maya Rossin-Slater (age 38) led the women with a time of 41:47.
