Leon Marchand Breaks US Open Meet Record: 3:44.70 400 Free | Race Breakdown & Key Splits (2026)

Hold onto your swim caps, because Leon Marchand just made waves in the swimming world! The 2025 U.S. Open witnessed a record-shattering performance as Marchand blazed through the 400-meter freestyle, clocking an astonishing 3:44.70. But here's where it gets even more thrilling: this time not only secured him the gold but also smashed the US Open Meet Record previously held by Zane Grothe since 2016. And this is the part most people miss—Marchand’s strategy was a masterclass in pacing, as he surged ahead of the record pace right from the start, particularly dominating the first 100 meters with a 1.4-second lead. While his initial split was slower than his personal best, his back half was nothing short of spectacular, shaving nearly four seconds off his previous time. This raises a bold question: Is Marchand’s approach the future of long-distance freestyle racing?

Let’s dive into the details. The 2025 U.S. Open, held from December 3-6 in Austin, Texas, at the Lee and Joe Jamail Texas Swimming Center, was a showcase of elite swimming talent. With prelims kicking off at 10 a.m. EST and finals at 7 p.m. EST (5 p.m. on Day 1), the event was a long-course meters (LCM) competition that drew swimmers from across the globe. For those who couldn’t attend, live results, psych sheets, and recaps were readily available online, ensuring fans didn’t miss a stroke. Speaking of strokes, Marchand’s performance wasn’t just about breaking records—it was about redefining what’s possible in the pool.

Here’s a breakdown of the top 8 finishers in the Men’s 400 Freestyle Finals:
1. Leon Marchand (TXLA) — 3:44.70
2. Luka Mijatovic (PLS) — 3:45.30
3. Carson Foster (UN) — 3:45.73
4. Luke Hobson (NYAC) — 3:45.85
5. Aaron Shackell (IU) — 3:47.93
6. Ilia Sibirtsev (UZB) — 3:48.98
7. Luke Whitlock (IU) — 3.48.99
8. Jordi Vilchez (OSU) — 3:51.49

While Marchand’s victory is undeniable, it’s worth noting that he hasn’t competed in the LCM 400 freestyle at major international meets. However, his NCAA record in the SCY 500 freestyle (4:02.31) hints at his versatility and potential on the global stage. This begs the question: Could Marchand become a dominant force in both short and long-course events?

A split comparison between Marchand’s record-breaking swim and Zane Grothe’s 2016 record reveals fascinating insights. Marchand consistently stayed ahead of Grothe’s pace, particularly excelling in the latter half of the race. This strategic pacing not only secured the win but also showcased his ability to maintain speed under pressure. For beginners, this highlights the importance of pacing in long-distance races—a lesson that could revolutionize training strategies.

As we reflect on Marchand’s achievement, it’s impossible not to wonder: Are we witnessing the rise of a new freestyle legend? Share your thoughts in the comments—do you think Marchand’s approach is a game-changer, or is there room for improvement? One thing’s for sure: the swimming world will be watching closely as he continues to make waves.
