Thomas Heilman Breaks Chas Morton’s Last National Age Group Record in Yards

12-year old Thomas Heilman from the Piedmont Family YMCA in Virginia has broken the 11-12 National Age Group Record in the 100 yard butterfly on Sunday. Swimming at the CYAC November Invite, Heilman touched in 51.44, which breaks Chas Morton‘s 1984-set record of 51.85.

That was the last yards record belonging to Morton, who was one of the great age group swimmers in US history. He still holds the 100 fly record for 11-12s in long course meters at 58.74, but all of his swims in yards have been erased. After his decorated age group career, Morton was part of an NCAA Championship team at Stanford in 1993.

Heilman’s previous best time was a 53.21 set in March of this year. He’s already been 59.89 in long course as well. He doesn’t age up until the new year, so he should have more opportunities to break records.

Heilman also swam a lifetime best of 48.35 in the 100 free this weekend, and a lifetime best of 4:20.91 in the 400 IM. The National Age Group Record in the 100 free is 47.89, so he’s now moved within half-a-second of that record as well.

Heilman’s other swims this week:

  • 500 free – 4:51.97
  • 100 breast – 1:03.72
  • 200 back – 2:05.20
  • 400 IM – 4:20.75
  • 100 free – 48.35
  • 200 breast – 2:21.15

Bearly Breathing

I remember reading about Chas Morton’s seemingly monthly accomplishments in Swimming World magazine in the 80s. The paper, hold-in-your-hand kind. I was in awe that a kid younger than me could swim so fast. Sometimes I wondered if his times were typos. It’s a testament to his talent that his records lastest for decades. But as we all know, someone will always go faster – you sometimes just have to wait a while. Congratulations Mr Heilman.


I have been lucky to watch Thomas at swim meets. He is a special kid in and out of the pool with an incredibly supportive family. In addition to Thomas, there are numerous other talented age group swimmers being developed at Piedmont Y.


Agreed on both accounts. Great kid. Great family. Lot of talent in Cville
