Disclaimer: Dolfin 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 Dolfin Swim 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.
Brazilian 21-year-old distance swimmer Guilherme Costa unofficially broke the South American record last week in a practice time trial of the 800 short course meter free. Costa crushed his previous best time of 7:45.29, going 7:39.84. That makes him (unofficially, of course) the fastest South American ever by almost three seconds.
Costa’s time would crack the top 10 in the world this season, if it were official. Costa is a fast riser who would likely have been contending for Olympic medals in distance free this month if the Olympics were still on schedule. Now, Costa gets one more year to hone his improvements before seeking what would be his first-ever Olympic medal in Tokyo next summer.
