Carson Foster is a competitive swimmer who represents the United States internationally. He is a World Junior Champion in the 200 IM and an NCAA champion as a member of the 4×200 free relay.

From a young age, Foster was at the top of his age group, making headlines when he broke Michael Phelps’ 10-under National Age Group record in the 100 fly just after becoming the youngest swimmer ever to break 30 seconds in the 50 fly.

Carson was ranked as SwimSwam’s #1 NCAA recruit in the college class of 2020. On March 7, 2018, Foster announced his verbal commitment to swim for Texas, just a month after his brother Jake had announced the same.
