Practice + Pancakes
In March of 2022, SwimSwam traveled to Charlottesville and filmed an episode of Practice + Pancakes with Cavalier Aquatics, in which Heilman (still 14 at the time) swam a 48-second 100y fly 3 times over the course of the workout.
2022 International Team Trials
At the USA Swimming International Team Trials in April, Heilman qualified for the United States roster for the 2022 Pan Pacific Swimming Championships in three events – 100 fly, 100 free, and 200 fly.
2022 Jr Pan Pacific Championships
At the Jr Pan Pacific Championships, Heilman joined Henry McFadden, Daniel Diehl, and Kaii Winkler to break the World Junior Record in the 400-meter freestyle relay on the meet’s first day. Heilman went on to win the 100 fly, breaking the US NAG (formerly held by Luca Urlando) and becoming the youngest swimmer ever under the 52-second threshold, going 51.96.
Heilman also earned silver in the 200 fly (1:56.52) and the 100 free (49.06, breaking another NAG) and as a member of the 800 free relay. Heilman capped his meet with gold in the 400 medley relay.
2022 Winter Jr Championships – East
Heilman once again had a historic meet at the Winter Jr Champs. On day 1, Heilman, as a 15-year-old, swam a 1:41.71 in the final of the 200 IM. This took over a second off of the old 15-16 NAG, held by Michael Andrew.
On Day 2, Heilman clocked a 44.67 in the 100 fly final. That not only shattered the 15-16 NAG of 45.62 held by Luca Urlando, but it was also faster than the 17-18 NAG of 44.75 held by Aiden Hayes.
On the final day of the meet, Heilman made it 3-for-3 as he touched in the 200 fly at 1:40.86, dipping under the mark of 1:40.91 held by Luca Urlando.
For all of his success, Heilman won the 2022 Swammy Award for 15-16 Male Age Group Swimmer of the Year.
2023 VA High School Class 4 State Championships
During his sophomore year at Western Albemarle High School, Heilman won individual titles in the 50-yard freestyle and 100-yard butterfly at the 2023 Virginia High School Class 4 State Championships. His swims contributed to Western Albemarle’s team title.
2023 U.S. International Team Trials (Indianapolis, Indiana)
Heilman had a massive swim in heat 4 of the 200 fly, stopping the clock at 1:55.11 for the second seed heading into finals. He dropped 1.41 seconds from his previous best of 1:56.52 from last summer and moved up to #2 on the American boys 15-16 all-time list, passing both Luca Urlando and Andrew Seliskar. Now, only Michael Phelps has been faster at his age, with the NAG standing at 1:54.58 from 2001. In the final, Heilman chased down Trenton Julian with a fantastic final underwater and last 50 to break Phelp’s NAG with a remarkable 1:54.54. The swim also qualified him for World Championships, becoming one of the youngest boys to make the top international team for the US since the aforementioned Phelps.
Heilman impressed again in the 100 fly on day 3. He bettered his own NAG with a 51.78 in the prelims to make the A final tied 6th. In the final, Heilman passed Shaine Casas over the back 50 with a 27.14 to destroy his own NAG and earn another race at Worlds with a 2nd place finish in a stunning 51.19.
2023 World Aquatics Championships (Fukuoka, Japan)
In 2001 at the World Championships here in Fukuoka, a young Michael Phelps destroyed the field in the 200 fly to make his name known across the swimming world. 22 years later, Thomas Heilman made his name similarly known. In the 200 fly, he was solid in prelims (1:55.59) and semis (1:54.57). In the final Heilman swam a beautiful race to go 1:53.82 and tie for 4th with Ilya Kharun. The swim makes him the fastest ever 18 and under from America at just 16 and the #4 American all-time. Heilman had already beaten the Phelps 15-16 NAG record of 1:54.58 that set the world record and won 2001 Worlds at the US Trials meet in 1:54.54.
| Splits | Heilman – World Champs Finals | Heilman – U.S. Trials Finals |
| 50m | 25.31 | 25.46 |
| 100m | 54.38 (29.07) | 54.20 (28.74) |
| 150m | 1:24.12 (29.74) | 1:24.50 (30.30) |
| 200m | 1:53.82 (29.70) | 1:54.54 (30.04) |
| FINAL TIME | 1:53.82 | 1:54.54 |
In the 100 fly, he was off his best time with a 51.77 to tie for 16th in the prelims. In a swim-off against Jacob Peters of Great Britain, Heilman improved with a 51.66 but Peters was better and Heilman missed the semis. On the pelims 400 medley relay, Heilman split 51.61. The finals squad netted gold, earning Heilman his first senior international medal.
THOMAS HEILMAN UNPACKS HIS 1ST WORLD CHAMPS PERFORMANCE:
2024 US Olympic Team Trials (Indianapolis, Indiana)
2024 US Olympic Team Trials (Indianapolis, Indiana)
In his signature 200 fly, Heilman cruised through prelims with a 1:56.77 for 8th. In semis, Heilman took control with a 1:54.93 for 2nd behind Luca Urlando’s 1:54.64. In the final, Trenton Julian, known for going out fast, did not deviate from his game plan and attacked the opening legs of the race. Julian was out in 25.04 and was 53.33 at the 100, leading Heilman by .74. He opened with a 25.35/28.72. Heilman continued to sit 2nd behind Julian at the 150, splitting 29.84. Down the stretch, Julian faded hard to 7th, leaving a clear path between Heilman and Paris. His 30.59 closing 50 was the fastest in the field as he lived up to the hype and qualified for his first Olympics with a 1:54.50. That made him the youngest American male swimmer to qualify for the games since Phelps (15) and Piersol (17) in 2000.
In the 100 fly, Heilman almost seemed out of doubling up, swimming a mere 52.30 for 11th in prelims and just making the final in 7th with a 51.58. Heilman was all the way back in 7th at the 50 with a 24.23 but crushed a massive, field-leading 26.57 back half to pass past 6 swimmers to finish 2nd, .61 seconds behind Dressel, with a 50.80. He out-touched Dare Rose by just .04 seconds. That took .39 seconds off his PB and claimed the NAG record from Phelps.
