For the 2nd-straight night, Brazilian freestyler Guilherme da Costa has broken a Brazilian and South American Record. His latest effort came in the men’s 400 free, where he swam a 3:46.57 to win the A-final on Thursday evening.
That swim smashed the old record of 3::47.99 that was set in April of this year at the Maria Lenk Trophy by Fernando Scheffer.
Costa’s closing speed in his swim was the difference-maker in the record. He also swam a South American Record of 7:47.37, where he also came way down in his closing 100 meter split (59.02 to 57.17).
Comparative Splits:
| Old Record | New Record | |
| Fernando Scheffer | Guilherme Costa | |
| 100m | 55.07 | 55.34 |
| 200m | 57.83 | 57.67 |
| 300m | 57.86 | 58.02 |
| 400m | 57.23 | 55.54 |
| Total Time | 3:47.99 | 3:46.57 |
Costa was 21st at the World Championships in the 800 free and 25th in the 1500 free.
Costa is one of a handful of Brazilian swimmers who are racing at this meet after spending some time at an altitude training camp in Flagstaff, Arizona. In Brazil, a country best known historically for its sprinters and almost never for its distance swimmers, have begun to see a wave of talented young swimmers shift that perception. That includes Costa, Scheffer, and 15-year old Stephan Steverink, who swam a 15:26.77 in the 1500 free at the Brazilian 15-16 championships this week.
