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.
14-year-old Sandpiper of Nevada Katie Grimes had an incredible 400 IM last week, moving to #3 all-time in the 13-14 age group.
Grimes went 4:09.27, moving to within a second of a 16-year-old National Age Group record. That record is held by an age group legend: Katie Hoff, who made the U.S. Olympic team at age 15 and ultimately won three Olympic medals and seven World Championships golds in her career.
The swim for Grimes was a massive time drop. Her previous best time had been a 4:14.67, set as a 13-year-old in December of 2019. Coming out of a pandemic-restricted summer, Grimes crushed more than five seconds off her best time. She leapfrogged a number of really notable names in the all-time 13-14 ranks with that swim:
