Imagine a swimmer who dominates not just one or two events, but nearly every stroke in the pool—could this be the ultimate versatile athlete we've all been waiting for?
Dive into the incredible story of Belgian swimmer Roos Vanotterdijk, a 20-year-old sensation who's shattering records across the board. With an impressive tally of 13 national records under her belt in both long course (open water-style pools, often used for Olympics) and short course meters (smaller pools for indoor meets), she's proven she's no one-trick pony. What's even more remarkable is her mastery over all five strokes: freestyle, backstroke, breaststroke, butterfly, and individual medley (IM), where swimmers combine all four strokes in one race. Think of IM as a thrilling medley, like a musical jam session where each stroke takes its turn—it's a test of endurance and adaptability that few can ace.
But here's where it gets controversial: Is this level of versatility a game-changer, or does it dilute focus on becoming a true specialist in one area? Let's break it down. Vanotterdijk shines brightest in short course meters (SCM), where she holds national records in every stroke except freestyle. That's four out of five—backstroke, breaststroke, butterfly, and IM. In long course (LCM), she's claimed records in freestyle, backstroke, butterfly, and IM. For beginners in swimming, SCM races happen in 25-meter pools, making them faster and more intense with quicker turns, while LCM uses 50-meter pools, emphasizing endurance over sprints. Her broad range isn't just about quantity; it's about excelling in events that demand different skills, like the explosive power in butterfly or the steady rhythm in breaststroke.
To give you a clearer picture, here's a detailed look at her Belgian National Records:
Short Course Meters (SCM):
- 50 backstroke: 26.43 (set in 2025 at World Cup Westmont)
- 100 backstroke: 56.78 (from 2024 Belgian Championships)
- 200 breaststroke: 2:18.07 (achieved in 2025 at Belgian Championships)
- 50 butterfly: 25.32 (2024 Danish Championships)
- 100 butterfly: 55.64 (2025 World Cup Carmel)
- 100 IM: 57.41 (2025 World Cup Westmont)
- 200 IM: 2:05.81 (2025 World Cup Toronto)
Long Course Meters (LCM):
- 100 freestyle: 53.62 (2025 Flanders Cup)
- 50 backstroke: 27.67 (2025 World Championships)
- 100 backstroke: 58.97 (2025 Flanders Cup)
- 50 butterfly: 25.32 (2025 World Championships)
- 100 butterfly: 55.84 (2025 World Championships)
- 200 IM: 2:09.73 (2025 French Championships)
Does this extensive collection of records crown her as the world's most versatile swimmer today? It's a hot topic, and opinions are divided. Many swimmers hold national records in multiple strokes, but Vanotterdijk's spread is unparalleled. Take Leon Marchand, the French star known for his powerhouse performances. He owns French records in long course 200 breaststroke, 200 butterfly, 200 IM, and 400 IM. In short course, he's got 200 backstroke, 200 breaststroke, 100 IM, 200 IM, and 400 IM. That's at most three strokes per course and four in total—impressive, but he lacks a freestyle record. Back in February 2023, Marchand even led the NCAA in seven events across all five strokes, including 500 freestyle, 100 backstroke, 100 breaststroke, 200 breaststroke, 200 butterfly, 200 IM, and 400 IM. It's similar to Vanotterdijk's versatility, though those weren't record-breaking swims at the time.
Then there's Kate Douglass, the American phenom with world records in the 100 freestyle and 200 breaststroke SCM, plus the U.S. record in 200 IM. Her combo is one of the most eclectic world record sets ever, blending speed in free with the unique challenges of breaststroke and IM. Yet, even she doesn't cover the full range of strokes like Vanotterdijk does.
And this is the part most people miss: While many elites stick to freestyle plus one other stroke, or maybe add IM, true all-around dominance is rare. Iconic swimmers like Michael Phelps won Olympic golds in freestyle, butterfly, and IM, but few are national bests in all four strokes plus IM. Vanotterdijk isn't just historically dominant for Belgium; she's world-class. At the 2025 World Championships, she snagged silver in the 100 butterfly and bronze in the 50 butterfly. In October's Swimming World Cup, she collected eight bronze medals across the 50 and 100 butterfly plus 100 IM over three meets. Add in her bronze from European Championships in the 100 backstroke, and European Juniors in the 100 freestyle and 50 backstroke.
The only stroke missing from her international medal haul is breaststroke, but that's because it's new to her. She raced the 200 breaststroke for the first time this year after a break since December 2019, and smashed the Belgian SCM record with a 2:18.07 at the 2025 Nationals. That time ranks fifth globally this season—and would have placed fifth last year, even against the Short Course World Championships. For context, breaststroke requires a rhythmic glide that's tricky to master, and her quick rise shows her adaptability.
Looking ahead, Vanotterdijk is one of seven Belgians competing at next week's European Championships. She's entered in the 50 butterfly, 100 IM, 200 freestyle, 100 butterfly, 200 breaststroke, 100 backstroke, 200 IM, 50 backstroke, and 50 freestyle. She might not tackle all, but she's a real contender for medals in every single one—a testament to her well-rounded prowess.
But let's stir the pot: Is versatility like Vanotterdijk's the future of swimming, or does it come at the expense of specializing deeply enough to take down legends like Phelps in their prime? Some argue that spreading talent across strokes makes athletes jacks-of-all-trades but masters of none, while others see it as the ultimate evolution in a sport demanding total pool dominance. What do you think? Does her record-breaking range make her the most versatile swimmer alive, or should we value specialists more? Share your thoughts in the comments—do you agree she's unparalleled, or is there a counterpoint I'm missing? Let's dive deeper into the debate!
