The Throws of a Record-Setting Season

While other kids have basketball hoops in their driveways, Cullen Prena and his sisters have a discus ring.
“I wish,” Cullen said Wednesday when asked if it was so.
You won’t find shot put craters in the family's lawn either.
But drive past the Prenas’ home when his sisters are home from college, and there’s a chance you’ll catch the Walled Lake Central junior and his Big Ten thrower siblings, Kari (University of Michigan) and Kelsey (Michigan State), talking over their craft.
“My sisters got me into it,” Cullen said. “It was a random summer day, and they were going to Central to throw. They asked me if I wanted to go with, and I said ‘Sure.’
“Ever since then I’ve been all into it. It’s basically taken over my life.”
Those first tosses came in the summer before Prena entered seventh grade. Five years later, he’s making a bid to go down as Michigan’s top high school thrower of all-time.
The fifth-place finisher in discus at last season’s MHSAA Division 1 Final Meet, Prena quickly has established himself as a heavy favorite this spring. He receives a Second Half High 5 this week after throwing an incredible 187 feet, 7 inches to win discus at Saturday’s Oxford Invitational, on top of also winning the shot put with a toss of 52-1.
Earlier in April, Prena topped 180 feet in discus two more times, in the process breaking both his school and then the Oakland County records that had both stood for at least 29 years according to a report by the Oakland Press.
And here’s the kicker: Prena’s top discus throw last season was a solid – but compared to now, mere – 159-9.
“His increase over the course of time, the average spectator can’t see it. But from sixth grade, he’s been training,” said Walled Lake Central boys track coach Nebojsa Stojkovic, who also works with the team’s throwers.
“You know how to gauge kids based on worth ethic and what their bodies are able to do. When freshman year he threw 144 feet, I knew the talent that was coming up.He’s got God-given ability that’s different from everyone else.”
That combination has made Prena something to behold this season.
His work ethic has benefited him with an increase in strength, evidenced by 30-40 percent improvements in all of his weight room lifts over the last year. Prena formerly played football, basketball and baseball, but decided to focus solely on weight training for track this school year in part after tearing a meniscus during his sophomore football season.
And then there’s two natural gifts for a thrower – Prena is double-jointed, allowing him increased flexibility for a stronger whip motion on his discus tosses. He also gets additional power from a wingspan that measures longer than his 6-foot-2 height.
He threw well at indoor competitions during the winter, and was tossing the discus consistently in the 170s when outdoor practice began this spring. In his team’s first meet, against White Lake Lakeland, he threw the discus 177 and then a best of 184-7, and also tossed the shot put 52-10 – more than three feet better than his previous outdoor personal-best in the latter event.
“It was hard to sleep (at night) after a meet when you throw a great throw like that,” Prena said.
Aside from some tires during workouts, Prena hasn’t tried tossing other heavy objects. “Other than my parents and my sisters; that’s about it,” he said, joking, of course.
But he's in serious pursuit of the MHSAA Finals record for discus. Prena’s best toss this season would’ve won every MHSAA Final dating back to 2003 and all seven of last season’s Finals (four Lower Peninsula, three Upper) by at least a foot.
That Finals record of 197-11 belongs to former Portage Northern standout Joey Sarantos, who set it in 2001. Prena must improve another 11 feet – which seems like a logical next step after this spring's gigantic 28-foot jump.
“Last year’s state meet ... didn’t quite go the way I wanted it to, and it’s been in the back of my mind since then,” Prena said. “Coming off of weight training, I kinda expected (the improvement). But you don’t know until you see the stuff. And then I started realizing it, and it was setting in that this is real. This is ridiculous."

Van Valkenburg Returns to Madison to Continue Dad's Pole Vaulting Program

Larry Van Valkenburg had two passions in retirement – coaching high school track & field and racing motorcycles.
In September, only a few months after completing his 25th season as the pole vault coach at Adrian Madison, Van Valkenburg loaded up his motorcycle and headed to Harpster, Ohio, a tiny, unincorporated city of 160 residents in central Ohio.
“He loved racing motorcycles,” said his son, Trevor Van Valkenburg. “Seems like an odd hobby for someone in their 70s, but he loved it. He hadn’t done it for a couple of years and said he wanted to give it one more shot.”
While at a race in Harpster, Van Valkenburg, 78, was involved in a motorcycle crash, had trouble catching his breath and tragically died.
“He took a very hard fall,” Trevor said.
This spring, after months of deliberations, Trevor decided to end his nine-year run as track coach at nearby Onsted and take over for his father as an assistant at Madison. For all intents and purposes, he’s coming home.
“It really is like coming home,” Trevor said. “I have crazy Madison ties that go way back.”
Trevor was a big reason why his dad began coaching at Madison. He was a high school sophomore in the early 2000s when he switched from baseball to track.
“When Coach (Josh) Powers took over the program in 1999, Madison didn’t have pole vault,” Van Valkenburg said. “Most of the schools in the 1990s had gotten rid of it. As a sophomore, I said if you have pole vault, I’ll run track. That is how my dad got involved.”
Trevor knew his dad had some background in pole vault.
“He was a vaulter in high school,” he said. “He always told us he had the school record. He vaulted in the 1960s where he would land in a pit of saw dust. As a junior, he broke his arm vaulting. He had a scar he would show us from time to time. His proud accomplishment was he came back as a senior and set the school record.”
With Trevor a senior, the Van Valkenburgs were part of Madison’s run to a Michigan Interscholastic Track Coaches Association (MITCA) track & field team state championship.
“He ended up staying 25 years,” Trevor said, speaking of his dad. “He loved it.”
Pole vault is a tough event to learn – and teach.
“In my opinion, it’s probably the most complicated high school sport,” Trevor said. “There are so many variables, how long your pole is, what the wind rating is, the flex rating and you have to set up your steps. You can move the bar so you have to know where to put it. It’s almost impossible to do well without a good coach. There are too many things an outside person needs to watch and give you feedback on.
“I always tell the kids every time you focus on one thing in pole vault about 30 other things go wrong – and that’s fine. It’s a very complicated high school thing to do. If you don’t have a good coach, it’s really hard to be successful.”
Last year, Trevor’s son Noah was on the Trojans middle school track & field team and chose the pole vault as one of his events. His grandfather was able to coach him.
“I am thankful for that,” Trevor said.
Over the years, the elder Van Valkenburg coached numerous league, county and Regional champs. Trevor joined his high school friend, Kyle Cessna, at Onsted, first coaching the pole vault but later coaching distance runners and the Wildcats cross country team. Madison and Onsted were in the same league, the Lenawee County Athletic Association, for the last several years.
“Over the years my dad and I had plenty of good pole vault coaching and team battles,” Trevor said. “We were really competitive at first. Over time, that relaxed a little bit.”
Returning to Madison to coach was an emotional decision for Trevor.
“I’ve coached Onsted for nine seasons,” Van Valkenburg said. “It was kind of always in the back of my head that if my dad was ever done, I’ll go back to Madison. I knew he would hold on as long as he could. It didn’t end up the way we thought it would, but it finally happened and I’m back home.”
Another reason it is home is because his wife, Kathryn, has taught at Madison schools for more than 20 years. His younger son, Dominque, also attends Madison schools.
“When I’m here after school, my whole family is here,” he said. “My wife is in the building. My one son is getting out of elementary at 3:30, my other son is on the middle school track team.”
Larry Van Valkenburg was an ex-Marine who retired as an air traffic controller in 2011. His legacy will remain at Madison, mainly because he teamed with Powers and the rest of the coaching staff to form a powerhouse track & field program that won numerous league championships and made an impact at MHSAA Finals.
“Larry was a great coach,” Powers said. “Trevor is a lot like him. We are really happy he came back to coach.”
Trevor Van Valkenburg is the director of the Lenawee District Library, a system that has six branches and a bookmobile. They circulate more than 150,000 items a year. Each spring, he adjusts his schedule to allow for coaching. He feels at home at Madison – and the track & field athletes can take comfort knowing a Van Valkenburg is still coaching them.
“We’re pretty similar,” Trevor said. “I learned a lot of it from (my dad), so it makes sense we would be similar. We both are pretty laid-back people. We’re not going to scream in kids’ faces. I might be a little more drill-heavy instead of just practicing jumping over the bar. I learned everything I know from him.”
