Owner of State's All-Time Farthest Shot Put Aiming for National Record, Olympics

From the first time Montrose's Addyson Stiverson picked up the shot put at a sixth-grade track & field practice, it was clear there was something there.
Even if she wasn’t quite clear on the name.
“I ran at the first couple practices, and was like, this wasn’t for me,” she said. “They said, ‘You’re strong, try the heavy ball thing.’ I honestly never threw it like a baseball. It wasn’t impeccable, but I kind of knew the basics. I definitely had some sore elbows and shoulders.”
Five years later, Stiverson sits atop the record books as she’s thrown that heavy ball thing farther than any female in Michigan high school history.
Her personal best of 53 feet, 7½ inches, which she threw Dec. 13 at an indoor meet at Grand Valley State University, is nearly two feet farther than the previous record of 51-11 held by Byron great Sarah Marvin, according to MichTrack.org, which tracks records from all meets. (The MHSAA record book is for Finals meets only.)
And as she enters her junior outdoor season having already won the shot put twice and discus once at the Lower Peninsula Division 3 Track & Field Finals, Stiverson’s goals go well beyond the state’s borders.
“(Competing in the Olympics) is the goal,” Stiverson said. “Throwing in 2028 would be nice, but I think a good goal is to be a good contender in (2032). Even going to trials in 2028 and getting close to making the team would be a big win for me.”
It’s a huge goal, but not at all outlandish for Stiverson, who is already fielding scholarship offers from between 20 and 30 major Division I programs and is part of the Nike Elite Team, which includes 40 of the country’s top high school track & field athletes.
She also trains with Dane Miller at Throws University in Reading, Pa. Miller has trained two national champions and 12 World Team members.
“When he texted me like a month or two after we went out there and he was like, ‘I want to coach you,’ I was like, holy crap. I was kind of fan-girling for a moment,” Stiverson said. “He’s like one of the only reasons I throw as far as I do. When he first started coaching me, he was like, you’re not doing this anymore, we’re doing this. He cut out all the bad stuff.”
Stiverson’s 53-7½ would rank seventh all-time on the National Federation of State High School Associations list. The listed record there is 57-1¼, by Alyssa Wilson of New Jersey. But Wilson threw 58-1 during the summer after her senior year, and that’s the record Stiverson is chasing.
Plus a little more.
“She always has that goal in the back of her mind of breaking that 58-1,” said Adam Stiverson, Addyson’s father and Montrose’s girls track coach. “She kind of has a little future goal that no one really talks about it: Could a high school female thrower ever hit 60 feet?
“She wants to compete in college no matter what, and she wants to get better. There’s always room for improvement. If she can fix some things, get a little bigger, a little stronger, 60 feet could be possible. But let’s get 55 feet out of the way, 56 feet out of the way, 57 feet out of the way. If we can get to 57, then we can talk about that 60, because then we’d know that 58-1 is coming.”
While chasing down national goals, Stiverson has been dominating locally.
She’s never been beaten in the shot put during the high school season, and she’s never finished lower than third in the discus, despite it being much less of a focus for her, as she doesn’t want it to affect her form in the shot.
“I’m not going to lie, I don’t touch a disc that much,” Stiverson said. “I give it maybe 75-25, maybe 70-30 during the season. I feel like if I give it too much attention, it could mess up my shot.”
While throwing is her main focus now, Stiverson did play varsity basketball as a freshman and sophomore at Montrose. She also played football all the way through freshman year.
At 5-foot-9, her all-around athletic ability and explosiveness are a great base for her throwing ability, and while she hasn’t shown it off in a while, she can run, too.
On the day she set the Montrose school record for the shot put as a freshman, she also won the 100 meters at a Mid-Michigan Activities Conference quad meet.
“That was for team points,” Stiverson said with a laugh. “Our coach said, ‘One of the girls didn’t show up, we need you to run.’ And I had my spikes with me, so I did.”
Stiverson was the Division 3 Finals champion in the shot put both of the past two years, and won the discus in 2025 as well. She was runner-up in the discus as a freshman.
There are still two full seasons to go, but she’s on pace to become the first female thrower in the Lower Peninsula to win four Finals titles in the shot put.
“I think that was my biggest goal when I came into high school; I wanted to be a four-time shot put state champ,” she said. “When it does happen, that would be one of the coolest things. That was a dream.”

Gladstone's Karl Siblings Talented In Taking to Air in High Jump, Pole Vault

ESCANABA — Three members of the Karl family have shown over the last few years a major interest in taking flight – at least from a track & field sense.
Gladstone sophomore Andrew Karl and his sister, freshman Maggie Karl, have found success in high jump, following older sister Kristy Karl – the girls school record holder in the event.
The younger two siblings also have shined in pole vault, Maggie tying the school record and Andrew just an inch away from doing the same on the boys side.
Kristy Karl, who has cleared 5 feet in high jump several times this season, owns the school record in that event at 5-foot-1 set a year ago. She will try to surpass that at Saturday’s Upper Peninsula Division 1 Finals at Kingsford.
“I need to put everything together,” she said. “Every time before I jump, I go over what I need to do. I started jumping in middle school. I figured out three-stepping this year and got the whole thing down.”
Kristy, who will attend classes at Bay College this fall, won high jump at 4-10 in the Regional on May 16 in Escanaba, and Maggie shared third place with Sault Ste. Marie freshman Isabelle McCord, both also at 4-10. Kristy also helped Gladstone win the 400-meter relay (52.56) and was runner-up in the 100 hurdles (16.97) on a lean by Escanaba junior Ava Stahlboerger.
Maggie Karl matched the school pole vault record with a winning leap of 9 feet as did senior teammate Chelsey Demeuse, who was edged on a tie-breaker as the Regional concluded Wednesday.
Boys’ pole vault started 12 days earlier, but was suspended after an Escanaba vaulter received injuries in a mishap during the Regional.
“It feels good to get this in,” Maggie said. “It’s so close to the Finals, although I think this is pretty helpful. I just wanted to qualify. How high you go depends on how you run (during the approach). I don’t remember exactly how I got started, but started jumping in seventh grade and I think it sparked an interest.”
Andrew Karl has soared as high as 14-3 in the pole vault this season, just an inch shy of the school record set by Josh Syverson in 2009.
He cleared 13 feet, good enough for third place as the Regional concluded.
“Changing the routine was the most challenging part,” he said. “You schedule your practices in advance. Consistency is key in any event. It’s a matter of deciding when to go hard and when to back off. I had plenty of height, but didn’t have the consistency with my pole.”
Maggie said she and Josh practice each Thursday during the summer at the Gladstone track.
“I think it helps,” she added. “Josh gives me pointers. Kristy doesn’t come down to the track quite as often, but she comes as much as she can and helps me with high jump.”
Josh, who started vaulting in middle school, is about to finish his third year of jumping.
“I like a good challenge, mentally and physically,” he said. “The biggest thing is to not think of it at all while you’re jumping because it becomes second nature. It’s a real balancing act. You’ve got to stick with it. It’s about consistency and never giving up. You just keep going.”
