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.”

Ontonagon's Team Effort Nets 3 Relay Wins, 3rd Team Title in 6 Seasons

KINGSFORD — The Ontonagon girls withstood the challenge of retaining the Upper Peninsula Division 3 track & field title here Saturday, winning for the second straight year with 74 points.
Stephenson edged Munising 62-60 for the runner-up trophy.
“When you come to the Finals, everybody can do something special,” said Ontonagon coach Brian Amos. “This is our third title in six years. We have a bunch of good kids who do what’s asked of them. We’re super proud of the girls. That’s a team effort.”
The Gladiators won the 400-meter relay in 52.84 seconds, 800 (1:52.68) and 1,600 (4:28.41) on a sunny and warm day.
“We’re pretty excited right now,” said senior Kiirsa Kolpack, who anchored the 400 relay. “Our handoffs and chemistry are real good. Being in sync with each other makes a big difference. We had a breeze kind of drifting on the south end of the field, which kind of cooled us off a little.”
Ontonagon’s Lilly McIntyre won the 100-meter dash in 13.7 seconds, edging Dollar Bay’s Ashlea Datto by one tenth of a second.
Kolpack was runner-up in the 100 hurdles (17.36), and Violet Amos placed second in the 400 (1:01.58).
Stephenson’s Jada Kuntze took high jump at 4 feet, 10 inches, and second in the 800 (2:34.99), and Daisy Grinsteiner added a first in pole vault (8-0).
“This is our first U.P. trophy since 1993,” said Stephenson coach Kate Kuntze. “This is a young team, and these girls like winning. Hopefully, we can take the next step next year. We have work to do.”
Munising opened with a victory in the 3,200 relay (11:23.25), and Monique Brisson took second in the 3,200 (13:15.72).
Purdue Northwest recruit and Rock Mid Peninsula senior Landry Koski gained her third straight 1,600 title in a season-best 5:31.74 and added firsts in the 800 (2:32.19) and 3,200 (12:52.73).
“The weather was nice all day, then it got hot in the 3,200,” she said. “The wind definitely swirled throughout the day – although, I’m real happy with how today turned out. The 400 could have been a little better. That’s not really my race, but it’s good speedwork. I’ll take the three firsts any day, and my times were real good. This is a good stepping stone for collegiate running. Running is such a mind game. It can be so stressful.”
Lake Linden-Hubbell freshman Emily Jokela won the 400 in a school-record 1:00.45 and 300 hurdles (47.78), and placed third in the 100 (13.78).
Teammate Abi Codere added a first in the 100 hurdles (17.19) and second in pole vault (8-0).
Brimley’s Grace Hill took shot put (34-10) and second in disc (101-1).
