Sound Running's The Ten returns to San Juan Capistrano, California on March 28 with the ambitious goal of hosting the fastest road 10K in the world once again. The event, which has rapidly established itself as one of the most innovative road races on the American calendar, features seeded sections of both the 10K and 5K for men and women, with professional pacemakers, a fast coastal course, and the kind of deep fields that produce personal bests across every section. This year's edition carries added intrigue with Shelby Houlihan headlining the women's 10K field as she targets the American record, marking another chapter in one of the most compelling comeback stories in recent US distance running history.
The men's 10K section features a deep field of American road specialists and emerging talent looking to establish early-season credentials ahead of the summer championship window. Sound Running's meticulous approach to pacing—using professional rabbits calibrated to hit exact splits—has made The Ten a go-to event for athletes chasing qualifying standards and personal records. The flat, net-downhill course along the scenic California coastline provides ideal conditions for fast times, and previous editions have produced some of the fastest road 10K marks on American soil. With live coverage on FloTrack, the event has also become a flagship broadcast property for professional road running in the United States.
The 5K sections add another dimension to the day's racing, providing an opportunity for middle-distance specialists and emerging road racers to compete over a distance that occupies an increasingly important space in the professional running landscape. The World Athletics Road Running Championships in Copenhagen later this year include a 5K event, and The Ten's 5K serves as an unofficial form guide for athletes eyeing selection. The combination of 5K and 10K racing across multiple sections creates a festival atmosphere that has become a hallmark of Sound Running events, drawing both elite athletes and knowledgeable fans to southern California each spring.
Sound Running, founded by Chris Chavez and a collective of running enthusiasts, has become one of the most influential forces in American professional road running. By combining smart course design, transparent pacing, premium broadcast production, and a deep understanding of what athletes and fans want, they have created events that punch well above their weight on the global stage. The Ten is their flagship, and each edition pushes the boundaries of what is possible in American road racing. The event's growing prize purse and increasing international participation suggest that it is only a matter of time before it attracts the kind of global elite talent that would put American road 10K records under serious threat.
Racing begins on Saturday morning with the women's 5K sections before building toward the marquee men's and women's 10K events in the afternoon. Weather forecasts suggest ideal conditions with mild temperatures and light winds off the Pacific, setting the stage for potentially the fastest edition of The Ten to date. For American distance running fans, the event has become an essential date on the spring calendar—a showcase of domestic talent, a proving ground for future championship performers, and a celebration of the road racing discipline that continues to grow in stature and commercial appeal. All eyes will be on Houlihan's American record attempt, but the depth of talent across every section means personal bests and breakout performances could come from anywhere in the field.
