Dolfin Swim of the Week: Carson Foster’s 3:38 in 400 IM

Disclaimer: Dolfin Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The  Dolfin Swim is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.

With a big slate of junior meets last week (East and West Winter Juniors, NCAP Invite), many of the key swims were viewed in that context – junior swimming. But several swims from last week legitimately hold up on the senior level. Carson Foster‘s 400 IM is one.

Foster went 3:38.65 to win the East Juniors title by seven seconds. He shattered his own meet record (3:40.86 from last year) and moved up to #2 all-time among 17-18s. Here’s a look at those rankings:

  1. Andrew Seliskar (2015) – 3:37.52
  2. Carson Foster (2019) – 3:38.65
  3. Chase Kalisz (2013) – 3:39.82
  4. Gunnar Bentz (2014) – 3:40.57
  5. Kieran Smith (2019) – 3:40.78
  6. Ryan Lochte (2003) – 3:41.45
  7. Robby Giller (2019) – 3:41.56
  8. Raunak Khosla (2019) – 3:42.22
  9. Dave Wharton (1988) – 3:42.23
  10. Jake Foster (2019) – 3:42.28

But Foster’s swim was also good enough to check in at #25 all-time of swimmers of any age. Only 14 men have broken 3:38 and only ten have broken 3:37.

That time also makes Foster far-and-away #1 in the nation this season, ahead of NCAA leaders Trenton Julian (4:40.05) and Braden Vines (3:40.09). In all of last season, only three men went faster than Foster’s time from Winter Juniors: NCAA champ Abrahm DeVine and top-3 finishers Sean Grieshop and Mike Thomas.

It was very cool to go back and look at those articles/videos. A lot of people mentioning other swimmers who have stayed relevant even now.
