The youngest competitor in the 400 meter IM field (long course) at the 2017 Southern Zone Sectional Championships in Plantation, Florida swam a 4:45.09 in prelims on Friday morning to break the 11-12 National Age Group Record.
Joshua Zuchowski, coached by his father Jonathan at Flood Aquatics, was the 8th-fastest swimmer in prelims (though he’s scratched the final). His swim took almost 6 full seconds from the old National Age Group Record of 4:51.03 set by Destin Lasco in 2014.
