Montana’s fastest man who started as a walk on

MISSOULA, Mt. — Karsen Beitz arrived at Montana with no scholarship offers, one remaining walk-on spot and no guarantee that his track career would last.

Now, the former Sentinel High School standout is one of the fastest athletes in Montana history.

Beitz, a Missoula native and junior sprinter for the Grizzlies, has turned an unlikely college opportunity into a record-setting career. He owns Montana’s 100-meter and 200-meter program records and enters next week’s Big Sky Conference Outdoor Championships as one of the top sprinters in the league.

Coming out of high school, Beitz was a football and track athlete without a Division I offer.

“I was upset about it,” Beitz said. “But at the same time, I was fine with just going to college and living a normal college life.”

That changed after conversations between Sentinel coach Dylan Reynolds and Montana coach Doug Fraley.

“You may not think he’s a D-I prospect based on his times,” Reynolds told Fraley, “but I’m just telling you, if he gets in the right program, he’s going to be a D-I runner.”

Fraley had one walk-on spot left on his roster. He brought Beitz into his office, talked with him and decided to take a chance.

“I liked him. We had a good conversation, so I decided to give him the last walk-on spot,” Fraley said. “I’m sure glad I did.”

Beitz became a Division I athlete in his hometown, but his first goal was modest. He wanted to prove he belonged and earn a scholarship.

He did that quickly.

As a freshman, Beitz placed at the Big Sky Outdoor Championships and helped Montana’s 4×100-meter relay reach the podium with a school-record performance.

“There was no doubt he earned that scholarship,” Fraley said.

Beitz continued to climb in 2025. He placed second in the 200 meters at the Big Sky indoor meet, but a hamstring injury kept him out of the outdoor championships.

“It sucked to deal with,” Beitz said. “But I’m young and still had two years left, so I shifted my mindset to how I could come out these next two years.”

He has not looked back.

Beitz won the 200 meters at the 2026 Big Sky indoor championships, the first individual conference title of his track career. His time of 21.09 seconds edged Idaho State’s Alex Conner by one-hundredth of a second.

“I think the best part about it was seeing how happy Doug was,” Beitz said. “He was jumping up and down, gave me a big hug. After last year, I knew what I was capable of, so to go out there and do it was amazing.”

Then came the outdoor season.

In April, Beitz broke Montana’s 58-year-old 200-meter record, running 20.55 seconds at the Pacific Coast Intercollegiate in Long Beach, California. The previous record had stood since 1968.

Two weeks later, he added the school’s wind-legal 100-meter record, running 10.25 seconds at the Bengal Invitational in Pocatello, Idaho. Which broke a 44-year-old program record and gave Beitz both sprint marks.

“He’s a really competitive guy, and he wants to be the best in the Big Sky,” Fraley said.

The records have not left Beitz satisfied. They have made him hungrier.

“You have all these goals and numbers in your mind,” Beitz said. “Then once you hit those numbers, you’re not satisfied. There’s just more numbers to chase.”

The next chase begins at the Big Sky Conference Outdoor Championships, scheduled for May 13-16 in Portland, Oregon.

After college, Beitz hopes to follow his mother’s footsteps and become a pharmacist. Maybe even the world’s fastest pharmacist.

“If I’m running around the hospital talking to doctors,” Beitz said, “I’ll do it pretty fast.”

From a walk-on few people noticed to a conference champion and school-record holder, Beitz has become Montana’s fastest man — and he is not done running.
