True Sweetser is one of the U.S.’ most promising up-and-coming distance freestylers. At 19 years old, he qualified for his first World Championships after taking the National title in the 1,500 meter freestyle. Sweetser was destined for swimming success. The youngest of six chose to swim at Stanford, after four out of five older siblings swam collegiately at an Ivy League School. His older brother Luke swam for Harvard while Seth, Marisa and Christian all swam for Cornell.
Sweetser began his career at Central Florida Marlins before joining Gator swim club when he was 15. A year later he was placed on the Junior National Team, add another year and he was named to the Senior National Team.
Sweetser made an immediate impact as a Cardinal, helping the team to win the Pac-12 Championships. He earned maximum points in the 1,650 yard freestyle, taking gold in 14:35.93. He also picked up points in the 500 yard freestyle with a silver medal in 4:14.11. However, at his first NCAA Championships, Sweetser was disappointed with a 12th place finish in the 1,650 yard freestyle after being seeded 5th and adding 5 seconds onto his time from the conference meet. He also finished 16th in the 500 yard freestyle, again adding time.
Sweetser made his international debut at the 2016 FINA World Short Course Championships. He made the final in the 1,500 meter freestyle, finishing 6th in 14:35.51.
At the 2017 U.S. Nationals, Sweetser claimed his first senior national title in the 1,500 meter freestyle to earn a spot on the World Championship team. He took the race out steady, and with 300 meters left to go he sat in fourth place. But that is when he turned the burners on, going sub 30 for the remainder of the 50 meter splits. He moved up to first place with 200 meters left to go and continued to pull away from the field to take gold in 14:59.73.
