Swim Record News Today

Brinegar competed in the 1500 freestyle in Tokyo after finishing in second at Wave II Trials. He swam a personal best tonight.

Marchand will return to France after altitude training at the OTC. After his 4:07 in-season 400m IM, how fast will he swim it at World Championships?

If you stopped someone on the street and asked them to name the world's best swimmer, chances are they would say Michael Phelps even if they didn't follow swimming. Phelps is a household name for all the records he has set, but a Texas high school student has just broken Phelps' 20-year NAG record.

Marchand's 1:56.95 took nearly a full second off the previous French Record of 1:57.89, which was set by now-retired Jeremy Stravius in 2013.

Nonetheless, Marchand's time of 4:10.38 lands very close to his personal best of 4:09.65, which he swam last summer.
