While competing on day one of the 2024 World Aquatics Swimming Championships (25m), 20-year-old Carmen Weiler Sastre produced a new Spanish national record in the women’s 100m back.
Racing in the heats, Sastre put up a time of 56.68 to nab the 7th seed for the next round this evening. That easily overtook the previous Spanish standard of 57.62 she established at a domestic meet last year.
This morning she cleared that former mark by nearly an entire second, with her front half crushing the 28.42 opening 50m in the previous swim.
| Sastre’s New Record – 56.68 | Sastre’s Old Record – 57.62 |
| 27.67 | 28.42 |
| 29.01 | 29.20 |
Sastre is no stranger to records, as the Olympian holds the LCM 100 back (59.57) and LCM 200 back (2:08.89) Spanish benchmarks as well.
