Katie Ledecky edged out rival Summer McIntosh in a thrilling women's 800-meter freestyle final at the World Aquatics Championships in Singapore. Ledecky's victory, clocking in at 8:05.62, prevented McIntosh from achieving five gold medals, a feat only Michael Phelps has accomplished. Australia's Lani Pallister also delivered a strong performance, finishing second. This race, considered one of the most significant non-Olympic swimming events, saw Ledecky extend her dominance in the 800m freestyle, adding another world title to her impressive collection.
