Amalie Smith, a 15-year-old out of Great Britain blasted a time of 4:37.02 in the girl’s 400 IM at the European Junior Championships to win the gold medal and become the fastest 15-year-old 400 IMer in British history, and the sixth fastest Brit of all time.

Smith took the gold medal by almost two seconds, pulling off a massive upset in the 400 IM over two-time defending champion Vivien Jackl of Hungary, who finished with the bronze.

Smith’s time was a personal best by more than four seconds, and it set a host of new records and vaulted her onto the all-time British rankings in the event. Starting with her own British Age Group Record for 15-year-old girls, which stood at 4:41.70 from January of this year.

She also obliterated the Championship record of 4:39.28, which Jackl set, winning her gold medal at last year’s Championships. Smith swam a very different race than Jackl’s record, starting off a second back after the butterfly, and dropping even further to four seconds back of record pace after the backstroke

Smith finished the breaststroke leg, a second-and-a-half ahead of record pace, making up more than five seconds in just one 100. Her freestyle split was also a bit faster than Jackl’s which brought her even more under that record time.
