Summer MacIntosh Age: How old is Summer Macintosh?

Summer McIntosh is a 16 years old competitive swimmer from Canada. She was born in August 18, 2006.

The young swimmer initially gained attention when, at the age of 14, she was the youngest member of Canada’s team for the 2020 Summer Olympics, where she finished fourth in the 400 metre freestyle.

The following year, she became the youngest world champion in over a decade and the first Canadian to win two gold medals in a single World Championships, earning her the moniker “teen swimming sensation.”

She established her first and second world records in the 400 metre freestyle and 400 individual medley events at the Canadian national trials in March and April 2023, in a five-day span.

Summer McIntosh has broken over 50 national age group swimming records. McIntosh swam a 4:05.13 in the 400 metre freestyle in May 2021, the fastest time ever by a 14-year-old swimmer worldwide.

She presently holds the women’s long course 400m IM world record. McIntosh successfully defended her 200 m butterfly championship on July 27 and improved on her world junior record in the 2023 World Aquatics Championships.

With the win, she became only the second Canadian, after Kylie Masse, to win three World titles, as well as the second to defend a World title, again after Masse.
