Colorado Springs-based pro runner Hillary Bor takes on first BolderBoulder in quest towards conquering the marathon
After an injury ended his steeplechase career, two-time Olympian Hillary Bor has a new focus: road racing.
What better way to immerse oneself in the road racing community than with one of the country’s most iconic races, the BolderBoulder 10k?
On Monday, Bor will participate in the pro race as part of Team USA’s Red Team for the International Team Challenge. In his first time ever racing in Boulder, Bor will join Conner Mantz and Biya Simbassa on the Red team, with Drew Hunter, Joe Klecker, and Aiden Reed making up the White team.
“I always wanted to do it, but scheduling never allowed,” Bor said. ”I’m really excited to run in Colorado, the place I’ve been training for the last 12 years and the place I call home.”
The BolderBoulder is another step in Bor’s goal of becoming a marathoner after recently turning to the roads following a foot injury during the 2024 Olympic Trials steeplechase finals.
“Once you break your foot it’s tough to learn to jump again,” Bor said.
In just under a year, Bor has already made a name for himself on the roads, breaking his own American 10-mile record in 2024 and running a 1:00.20 at the 2025 Houston Half Marathon for the sixth-fastest time in American history.
He hopes to make a statement on Memorial Day and help the United States win the team title.
“We are going to bring our A-game and make sure we win,” Bor said.
A pole vaulter and jumper in Eldoret, Kenya, Bor’s journey to road racing has been a long one.
With little opportunity to attend university in Kenya, Bor’s family of athletes encouraged him to pursue a running scholarship in America. Bor had only done the steeplechase once in Kenya, but was a natural and received a full-ride scholarship to Iowa State.
After a prolific track career in Iowa, the steeplechase specialist enlisted in the U.S Army where he was a sergeant at Fort Carson in Colorado Springs. The program Bor was a part of also allowed him to gain his U.S citizenship.
“For me, when I moved here, I was lucky enough to get a scholarship and go to school for free,” Bor said. “I wanted to be part of this great nation that gave me that opportunity.”
During his four year stint at Fort Carson, he competed for the Armed Forces team and in 2021, joined the U.S Army World Athlete Program, a military unit that allows soldiers to train and participate on Olympic teams.
Bor stayed in Colorado Springs, where he trains with other pro athletes and raises his two children, five and 7-years-old.
A typical “easy” day for Bor is waking up at 5 a.m. followed by a 12-14 mile run before getting his kids ready for school. Another run follows school pick-up.
“It’s beautiful here,” Bor said. “The weather is nice, we like to go to the mountains, it’s family friendly. …We plan to call it home for a while.”
Bor hopes to make another Olympic trial appearance in 2028, mostly because his kids will be old enough to understand the magnitude of the event.
“I want to give myself the chance to make the team,” the seven-time national champion said. “My daughter is starting to understand what I do, she watches my races on YouTube. She is starting to understand what I do for a living and I hope they can witness it on that stage.”
For now, Bor is excited to participate in the BolderBoulder, and particularly looks forward to the finish inside Folsom Field, which is reminiscent of his times racing in front of thousands on the track.
“It’s one of the biggest races in the world, so it’s a blessing to be selected for this race,” Bor said. “It shows the work I’ve put in is being appreciated. It’s exciting. One day I’m going to tell my kids ‘I ran in the BolderBoulder, but I wasn’t running as an individual, I was representing the U.S.’”
