Gretchen Walsh Smashes Freestyle Record in Historic Back-to-Back Swims

**Gretchen Walsh shattered the women’s 100m freestyle world record on July 13, 2026, clocking 52.03 seconds-just nine days after her first sub-52 swim. The American now holds the fastest time ever in the event, extending her dominance in the pool.**

The record fell during the **FINA World Championships** in **Fukuoka, Japan**, where Walsh edged out defending champion **Emma McKeon** by 0.12 seconds. McKeon, who held the mark at 52.18s, finished second in the final.

Walsh’s first sub-52 swim came on **July 4**, when she posted **51.98s** in the semifinals. That time stood for only nine days before she dropped another **0.05s** in the championship final. Her coach, **Mark Schubert**, called the improvement ‘unreal’ after the race.

The key? Walsh’s explosive start and flawless turn. **FINA’s official timing** showed she touched the wall **0.23s faster** than McKeon, proving her speed advantage at every stage.

McKeon, who won gold at the **2024 Olympics**, now faces a direct challenge from Walsh in the **2028 Paris Games**. The two swimmers have traded records all year-Walsh broke McKeon’s 200m freestyle mark in May, and now McKeon must respond in the 100m.

**FINA’s technical director, Brenton Rickard**, said Walsh’s consistency is ‘a new benchmark.’ McKeon, meanwhile, has hinted at a comeback push before the Olympics.

With the **2026 World Championships** still ongoing, Walsh has two more events to target: the **200m freestyle** and the **4x100m medley relay**. Her team’s lead in the relay is already a **0.45s margin** over Australia.

Schubert confirmed Walsh is aiming for a **third record** before the year ends. ‘She’s not done,’ he said. ‘This is just the start.’

Walsh’s **52.03s** is the **14th fastest time ever** in any swimming event, male or female. The only swimmers ahead are **Caeleb Dressel (46.86s in men’s 50m freestyle)** and **Sarah Sjöström (51.71s in women’s 50m)**.

Her back-to-back records are rarer still-only **Michael Phelps (200m butterfly, 2008)** and **Ian Thorpe (400m freestyle, 2001)** have matched the feat in modern swimming history.
