Swimming World Records

Jack Nunn, a former US national team rower who won silver in the eight at the 2001 Under-23 World Rowing Championships in Linz, Austria, finished three of triathlon's most punishing races in a little over two years. He completed the Norseman Xtreme Triathlon in Norway in 15:02:45 in August 2017, the three-day, 320-mile Ultraman Florida in 33:24:36 in February 2019, and the Ironman World Championship in Kona, Hawaii in 15:05:51 in October 2019. RecordSetter checked each finish against the official published race results, for a combined 63 hours, 33 minutes and 12 seconds. Not bad for a 6-foot-3, 220-pound athlete built for a rowing shell rather than a mountain climb.

Chengyong Wu was 14 years old when he left the block 0.49 seconds after the starting signal at the 2024 Olympic HKG Long Course Swimming Invitational Trial I in Hong Kong, racing out of lane 4 in the men's 200-meter individual medley. Reaction time measures the gap between the starter's tone and the swimmer's first movement, and it is registered by pressure sensors built into the starting block rather than judged by eye, so the figure that flashed on the official scoreboard is the block's own verdict. The whole record was over before he touched the water, which is a fine reminder that swimming races are decided in places nobody is watching.
