The 9th edition of the Marina Double Road Race delivered yet another memorable chapter along the scenic waterfront of Brisbane, as runners took to the flat and fast course on March 21, 2026. Set against the breathtaking backdrop of the San Francisco Bay, the event once again showcased the unique blend of competition, community, and pure running joy that defines this race.

From the opening strides at Sierra Point to the turnaround at Oyster Point and back, athletes were met with near-perfect conditions. Calm weather and a picturesque route created the ideal stage for both elite performances and personal triumphs, as participants across the Double 15K, 10K, 5K, and Kids Mile embraced the rhythm of the day.

Adding to its distinctive appeal, the Double 15K is a unique race concept created by Bob Anderson, designed to test both speed and endurance in a strategic format. Athletes first complete a 10K, then return 1 hour and 45 minutes later to race a 5K, with their combined times determining the final standings. Beyond overall results, the coveted Double Victory Cup is awarded to the runner who achieves the best age-graded performance—an element that celebrates excellence across all ages, highlighted this year by an outstanding victory from a 50-year-old woman, Ritsuko Tague who delivered 58:49, the top age-graded run of the day.

At the front of the field, the Double 15K produced a series of standout performances led by Anthony Cortes, who delivered a commanding run to win the men’s race in 49:42. He was followed by Harold Castiaux, whose strong and steady effort secured second place in 55:16, while Ben Kortlang claimed third in 57:35 with a determined finish. Fernando Wotari completed the top four, crossing the line in 1:07:50.

In the women’s race, Ritsuko Tague showcased both experience and strength, surging to victory in 58:49 with an impressive display of control. Bella Rogers followed in 1:08:37, highlighting her emerging potential, while Anitha Nanunda took third in 1:15:02 through a resilient performance. Julia Rogers rounded out the top four, finishing in 1:21:25.

Beyond the leading pack, the depth of competition across the age groups added another layer of meaning to the event. From the 40–49 to the 60–69 divisions, athletes demonstrated that excellence in running knows no boundaries of age, blending experience, discipline, and enduring passion into performances that were as inspiring as they were competitive.

More than just a race, the Marina Double 15K once again brought together a vibrant community united by a shared love of the sport. Familiar faces reconnected, new friendships were formed, and every finisher contributed to the spirit that makes this event truly special.

With the energy of this edition still fresh, the journey continues toward the next chapter on April 3, 2027—another opportunity to hit the road, chase new goals, and write fresh stories along the timeless beauty of the Bay.

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%.
