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%.
Other Race Highlights
The Marina event also featured three additional races open to the public.
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.
In the 5K Run/Walk, Joji Morikawa (age 21) won the men’s division with a time of 18:04, and Yannan Xi (age 38) was the first female finisher in 21:02.
The Bob Anderson’s Kids Mile, open to children 13 and under, brought smiles and strong performances. Dylan Nichol (age 11) was the fastest boy with a time of 6:43, and Nadia Slater (age 9) finished first among the girls in 7:54.
Held along the waterfront paths of Harbor Park in Brisbane, California, the Marina Double featured stunning views of the bay, mild spring weather, and a welcoming, community-driven atmosphere that brought together competitive runners and families alike.
