Swim of the Week is brought to you by arena, a SwimSwam partner.
Disclaimer: Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The Swim of the Week is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.
Czech sprinter Daniel Gracik blasted his way to a new National Record in the men’s 50 butterfly (SCM) last weekend at the Slovakia Swimming Cup in what was his first competition of 2025.
Gracik, who turned 21 just three days before the swim, clocked 22.48 to lower this previous Czech Record of 22.68, set at the 2023 European Short Course Championships in Otopeni.

The performance, which was done in the prelims and marked Gracik’s lone swim of the meet, moves Gracik into 12th in the 2025-26 world rankings and makes him the 41st-fastest European of all-time.
