This Teen Ultrarunner Wants to Take on the World's Most Prestigious Races

Last November, 17-year-old Sebastian Salsbury received an email reminder. He had 13 days to decide about entering the race lottery for the 2024 Western States 100 Mile Endurance Run, regarded as one of the most prestigious trail events in the world. 

Rules stipulate that each lottery applicant must be at least 18 years old on race day. On January 20, Salsbury will finally meet the age requirement, five years after he technically ran a qualifying time to enter the lottery for the first time.

It's been a goal he's been progressing toward for years. In 2020, when Salsbury was 13, he completed the Black Canyon 100K in Arizona in 15 hours 49 minutes and 32 seconds, well within the 17-hour time limit necessary to qualify for the Western States lottery. 

"It's hard to put that experience into words," Salsbury says. "It was one of the most beautiful courses I've ever been on. That race made me feel like I was doing the right thing in my life." 

Starting Young

Salsbury, who grew up in Santa Barbara, California, was attracted to the trails at a young age. Throughout his childhood, his parents often brought him to nearby trails to hike. The hikes gradually transitioned into jogs, and Salsbury's relationship with the outdoors continued to grow. The mountains, he says, were a playground.

Though Salsbury played basketball, football, and soccer growing up, his love for running took over. He quit the other sports after junior high school to minimize risk for injury, he says, and to dedicate more time to running.

A few years after Salsbury's entry into racing-his first was a local 5K on the road when he was four-he ran the Santa Barbara Red Rock Trail Run. Despite being just nine, he kept up with his father for all 28 miles. The following year, for the Santa Barbara Nine Trails, Salsbury traversed 35 miles with nearly 12,000 feet of vertical gain from the Jesusita trailhead to Romero Canyon trailhead and back, again alongside his father, a road marathoner.

Next, Salsbury entered the Black Canyon 100K in Arizona. He recalled the point-to-point race as one of his most difficult running experiences to date. 

"I was basically crying," Salsbury remembers, adding that his hydration vest kept digging into his ribs. "I loved the feeling of working hard and going through really low moments and overcoming them. I crave it."

Supported for the last 20 miles by his coach at the time, Tyler Hansen, Salsbury crossed the finish feeling both defeated and uplifted. The Black Canyon race gave him the confidence to continue challenging himself in ultrarunning.

"My best friends don't understand," Salsbury says about the pursuit of ultras, which he envisions including some of the most technically demanding and prestigious races in the world: the Western States 100 in California, Ultra-Trail du Mont-Blanc through the French Alps, as well as the Hardrock Hundred Mile Endurance Run in Colorado. Salsbury admits that running disrupts his social life, and also that he doesn't mind the solitude the sport necessitates. In fact, he welcomes it.

"I like the feeling of being alone in the mountains," Salsbury says. "It's a great way to free your mind."

Given that he is still a teen-the average age of trail runners is in the mid-30s-Salsbury has not been immune to negative comments over the years. "It's not cool at all to hate, but I can still see where someone would be coming from, seeing a kid doing all that stuff," Salsbury says. "There are going to be people that troll and hate for no reason. That's just life."

A Purposeful Progression

The training required to undertake ultras is out of this world for a typical high school runner. To ensure he's programming himself with sufficient miles without overloading his still-developing body, Salsbury sought the guidance of his longtime role model, pro trail runner Hayden Hawks. The two met when Salsbury was 14, and their camaraderie clicked naturally.

"I had lots of mentors help me at a young age in my running journey, and I felt the responsibility to do the same with Sebastian," says Hawks, 32. "We have taken a patient and gradual approach, developing strength, speed, and a foundation that will help him build into the longer distance races at an older age."

Hawks has coached Salsbury for the past two years, carefully mapping out a plan that tallies 50 miles weekly spread across six days. Salisbury complements the mileage with a combination of hiking, mountain biking, and intervals on an indoor bike as part of his cross training. Three days a week, he does strength exercises at Varient Training Lab in Santa Barbara. To fit it all in so he could have ample opportunity to train and compete, prior to the Covid-19 pandemic, Salsbury enrolled in West River Academy, an online private school program.

"I have zero regrets," Salsbury says. "The opportunity that it's given me to travel with my family and run and be able to guide my days how I want and learn at my own pace, I'm grateful for that."

The online program lasts up to three hours a day, which is "a lot less than standard high school," Salsbury chuckles. In 2022, he researched computer engineering and built a computer from scratch. This year, as part of the online curriculum, he's learning to speak German in addition to researching for a project about coffee and sustainability, which he is especially interested in as a part-time certified barista. Salisbury works at a local coffee shop twice a week. 

So far, he's enjoying the unique balance of online learning and ultrarunning. "I like to keep myself busy," he says. "I've always had this next-level energy. Obviously it goes into running, but it's who I am as a person." 

His days are hardly routine compared to the average high schooler. On a recent Thursday, Salsbury started the day with a three-minute cold plunge before he spent the remainder of the morning packing running shoes, thermal layers, his COROS watch, and a heart rate monitor ahead of a four-day trip to Boulder, Colorado, to train with a friend at altitude.

Living at sea level in Santa Barbara, Salsbury doesn't often have the opportunity to run at altitude beyond twice a year, mostly "just a vacation with my family where I get to do some running," he says.

As much as he has run over the years, Salsbury says he's been fortunate to never have had any serious injuries. This year, a growth spurt of eight inches led to severe shin splints, and Salsbury, who is now 6-foot-4 and 162 pounds, took four months off from running.

Now, life is back to business as usual. Salsbury is planning ahead. His next race is the La Cuesta Ranch 25K in San Luis Obispo, California, in late January. After he graduates from high school in June 2024, he wants to pursue a running career ideally full-time, though he hasn't stated when he aims to turn professional. 

"I've always had the intention to be one of the greatest ultrarunners in the world one day. That will continue to be my goal," Salsbury says. "I want to leave a positive impact on the sport and be an inspiration to other athletes of any age, but obviously the youth because that's how I grew up. People can judge and say whatever they want, but I do want to be the best of all time."
