At the 2023 Men’s NCAA Championship, Leon Marchand continued his dominance. After breaking the 400 IM and 200 Breast NCAA records earlier this season, we knew it was a matter of time before we broke the 200 IM record that he set in 2022. Using the FINA point projection system, this swim was the highest of the men’s meet with 1041 points (barely edging his 400 IM swim at 1040 points). In this post, I’ll analyze the 200 yard IM race and provide theoretical areas of improvement for Leon Marchand’s 1:36.34 200 yard IM NCAA Record.

For those who havenâ€™t followed one of our analyses, these analyses are for fun and to spark debate. There are some inherent flaws in this race analysis:

- Videos are taken from YouTube videos (often with subpar angles)
- There are analyzed with Kinovea

## 200 Yard IM NCAA Record Analysis

In one of the most anticipated races at NCAA’s, Leon Marchand demolished his previous record, making the other swimmers (even Destin Lasco who broke the American Record appear pedestrian).

## Theoretical Improvements for Marchand’s 200 Yard IM NCAA Record

There is room to improve for every swimmer. Here are the notable improvements from Leon Marchand’s 200 IM NCAA Record:

- After seeing Leon’s amazing backstroke turns and dolphin kicks, I am surprised he didn’t go 15-m on his start and butterfly turn. Maximizing this distance would improve his velocity and time for fly, but possibly reduce his fatigue in his freestyle leg. Improving this could improve his time by 0.05 – 0.15 seconds.

- The only other possible area of improvement for Marchand is his last 50 freestyle leg. As he mentioned in post race interviews, he was taking it ’50 by 50′ implying he was going fast for every 50. However, perhaps this strategy resulted in a significant impairment on his freestyle leg. Therefore, perhaps going out 0.1 – 0.2 seconds slower on his back and fly 50s could result in a 0.8 – 1.0 second faster freestyle leg (which he has gone 23.78 seconds in his freestyle leg at 2023 Pac-12 Championships). If he can adjust his race strategy slightly, he would improve 0.4 – 0.6 seconds.

With these improvements, she can improve another 0.45 – 0.75 seconds.

There are likely more technical improvements with his swimming stroke, but the video from the race is not close enough or provides underwater angles for a full assessment.
