The Boys 13-14 LCM record book was significantly rewritten between 2021 and 2024. Thomas Heilman set the sprint and butterfly marks in 2021. Luka Mijatovic then rewrote the distance free landscape in 2023 and 2024, taking the 200, 400, 800, and 1500 free as well as the 400 IM. The result is a record list where the most recently set marks carry strong recency protection.

Against that backdrop, this winter's SCY field is deep. Elliot Leasure leads the way across backstroke, butterfly, and IM. Ayden Tan — just 13 years old — appears competitively across six events. And a handful of event-specific specialists round out the picture.

The recurring theme on the boys side is a field with exceptional SCY speed that is still developing its long course conversion. Last-season LCM references are the honest measure of where things actually stand.

Sprint Freestyle

50 Freestyle — NAG: 22.95 | Thomas Heilman (2021)

Three sprinters are bunched tightly at the top of this event. Jesse Cyrus (14) leads at 21.16 SCY (24.29 projected), with a last-season LCM reference of 24.85 — about 1.9 seconds above the record on actual swims, which in the 50 free is a solid gap. Abram Webster (14) follows at 21.32 SCY (24.47 projected), with a last-season LCM reference of 25.72. Hank Cheng (14) rounds out the group at 21.34 SCY (24.49 projected), with a last-season LCM reference of 24.87 — the most advanced real sprint LCM time of the three, essentially matching Cyrus's projection.

Cyrus and Cheng are the real-performance leaders in this event, both coming off last-season LCM times in the 24.85–24.87 range. The record has about 2 seconds of real-world protection — not insurmountable on a multi-season horizon, but not close in 2026.

100 Freestyle — NAG: 51.12 | Thomas Heilman (2021)

Lubo Liu-Tchorbadjiyski (14) leads at 45.66 SCY (52.28 projected), with a last-season LCM reference of 53.30 — 2.18 seconds above the record on actual swims. He's the only candidate in this event with a real LCM time that projects credible development toward Heilman's mark. Ayden Tan (13) is second at 46.23 SCY (52.92 projected), with a last-season LCM reference of 54.91 — the former 11-12 NAG — showing he's been racing LCM competitively. Elliot Leasure (14) rounds out the group at 46.56 SCY (53.28 projected), with a 55.52 last-season LCM reference.

Liu-Tchorbadjiyski's 53.30 last-season LCM time gives him the most credible real-world baseline in this event. The record still has over 2 seconds of real protection, but he's tracking in the right direction.

Distance Freestyle

200 Freestyle — NAG: 1:49.63 | Luka Mijatovic (2024)

A 2024 record with strong recency protection. Elliot Leasure leads at 1:39.24 SCY (1:53.36 projected), 3.73 seconds above the record on paper. His last-season LCM reference of 2:02.56 — from a May meet — shows this event is still early in its long course development for him. Jude Burkhart (14) projects to 1:55.41, with a last-season LCM reference of 1:57.01 — the most grounded real long course 200 free time in this group, and the baseline that best reflects where the field actually sits relative to the record. Miles Ayres (14) is third at 1:55.96 projected, with a 2:06.84 last-season LCM reference.

Burkhart's 1:57.01 last-season LCM time leads the field in real performance. The record has roughly 7 seconds of real-world protection. Mijatovic's 2024 mark is well-guarded.

400 Freestyle — NAG: 3:51.18 | Luka Mijatovic (2024)

The 400 free field projects tightly — Rui Rui An, Declan McDonald, and Hanz Palattao all convert within a narrow window of 4:04.05–4:04.55 — but the record is over 13 seconds above even the top projection. An's last-season LCM reference of 4:15.40 and Palattao's 4:16.07 are the most developed real baselines; McDonald's 4:26.37 reflects very early-season LCM racing.

Mijatovic's 2024 mark is firmly protected. An and Palattao both went 4:15–4:16 last summer, which is where this field genuinely sits — a good 24 seconds from the record in real terms.

800 Freestyle — NAG: 7:59.64 | Luka Mijatovic (2023)

Jude Burkhart leads the 800 free field at 8:21.50 projected, with a last-season LCM reference of 8:38.39 — the most developed real long course 800 baseline in this group, and about 38 seconds above the record on actual swims. Damien Orfanoudakis (14) projects to 8:23.10, with a last-season LCM reference of 9:03.84 — a larger gap that suggests his long course distance form is still building. Declan McDonald rounds out the group at 8:24.76 projected with no last-season LCM reference available.

Burkhart's 8:38 last-season LCM time is the relevant real benchmark. The record has nearly 40 seconds of real-world protection — firmly safe this cycle.

1500 Freestyle — NAG: 15:26.73 | Luka Mijatovic (2024)

Jude Burkhart leads at 15:54.70 projected, with a last-season LCM reference of 16:24.76 — nearly a minute above the record on actual swims. Jax Capen (14) and Damien Orfanoudakis both project around 16:10–16:11, with Capen's 16:42.63 last-season LCM reference more advanced than Orfanoudakis's 17:11.35.

Mijatovic's 2024 1500 is the most protected distance record in this dataset — nearly 28 seconds clear of the top projection, and last-season LCM references a minute or more behind. Burkhart leads the field in real terms.

Backstroke

50 Backstroke — NAG: 26.70 | Jack Alexy (2017)

Elliot Leasure and Lubo Liu-Tchorbadjiyski both project under the record — 25.53 and 25.60 respectively — but their last-season LCM references of 27.72 and 27.30 show they were both above it in real competition last summer. Liu-Tchorbadjiyski's 27.30 is the more advanced real reference of the two. Ayden Tan (13) rounds out the group at 22.94 SCY (26.06 projected), with a 28.86 last-season LCM reference.

Liu-Tchorbadjiyski leads on real long course performance in this event. The record has about 0.6 seconds of real-world protection based on last summer — closer than most events in this dataset, and a genuine watch if both swimmers continue to develop.

100 Backstroke — NAG: 56.36 | Thomas McMillan (2024)

Elliot Leasure's projection of 54.16 from his 47.71 SCY is the most striking number on the boys side — 2.2 seconds under the record on paper. His last-season LCM reference of 57.78 tells the fuller story: he was 1.42 seconds above the record in actual competition last summer. That gap — from 57.78 to a projection of 54.16 — reflects the same SCY-to-LCM conversion question that runs through his entire profile. Ayden Tan (13) follows at 55.87 projected, with a 1:01.31 last-season LCM reference indicating very limited long course 100 back experience. Lubo Liu-Tchorbadjiyski is third at 55.98 projected, with a 59.88 last-season LCM reference.

Leasure's 57.78 last-season LCM time is the real starting point — he was 1.42 seconds above the record last summer. Closing that gap is plausible; his projection suggests the ceiling is much higher. This is the most interesting backstroke watch in the dataset.

200 Backstroke — NAG: 2:00.28 | Keaton Jones (2019)

Elliot Leasure projects to 1:57.76 — 2.52 seconds under the record on paper — with a last-season LCM reference of 2:07.32. That's a 7-second gap between his last-season LCM time and the record, which is a large step. Jaxson Daniel (14) follows at 2:03.15 projected, with a 2:13.35 last-season LCM reference. Ayden Tan (13) is third at 2:03.43 projected, with a 2:12.39 last-season LCM reference.

Leasure's last-season LCM reference of 2:07.32 is the most developed real baseline in this event — but 7 seconds from the record in actual competition is a meaningful gap. His SCY speed suggests potential well beyond last summer. One to track carefully.

Breaststroke

50 Breaststroke — NAG: 28.92 | Wilson York (2024)

A 2024 record with recency protection. Hanz Palattao (14) leads at 26.35 SCY (30.25 projected) with no last-season LCM reference available — an unknown long course baseline. Eli Henley (14) follows at 26.51 SCY (30.43 projected), with a last-season LCM reference of 31.03. Landon Williams (14) rounds out the group at 26.59 SCY (30.51 projected), with a last-season LCM reference of 30.20 — actually faster than his own projection, suggesting his real long course form is already ahead of where conversion math places him.

Williams's 30.20 last-season LCM time leads the field on real performance — within 1.28 seconds of York's 2024 mark in actual competition. The record is protected, but he's the most credible real threat in this event.

100 Breaststroke — NAG: 1:02.22 | Ian Call (2023)

Hanz Palattao leads at 56.51 SCY (1:04.73 projected), with a last-season LCM reference of 1:08.25 — about 6 seconds above the record in real competition. Ryan Yao (14) follows at 56.97 SCY (1:05.24 projected), with a 1:09.88 last-season LCM reference. Landon Williams rounds out the group at 57.24 SCY (1:05.54 projected), with a 1:08.65 last-season LCM reference — the most advanced real 100 breast LCM time in this group.

Call's 2023 record has 2.5+ seconds of protection over the top projection. Last-season LCM times in the 1:08–1:09 range confirm the field still has real development ahead before this mark is threatened.

200 Breaststroke — NAG: 2:15.11 | Wilson York (2024)

Ryan Yao and Hanz Palattao share identical SCY bests of 2:03.19 and identical projections of 2:20.74 — a genuine statistical tie at the top of this event. Their last-season LCM references distinguish them: Palattao at 2:26.69 and Yao at 2:28.40, with Palattao holding a slight edge in real long course competition. Frederic Burks (14) is third at 2:21.30 projected, with a last-season LCM reference of 2:26.61 — nearly matching Palattao's real baseline.

York's 2024 record has 5+ seconds of protection over the top projections. The more interesting story is Palattao and Burks both showing 2:26 last summer — their head-to-head development across the season is the internal competition to follow.

Butterfly

50 Butterfly — NAG: 25.26 | Brady Campbell (2023)

Lubo Liu-Tchorbadjiyski leads at 22.24 SCY (25.39 projected) — just 0.51% above the record on paper, the tightest projection gap in the boys dataset. His last-season LCM reference of 26.26 puts him 1 second above the record in real competition. Ayden Tan (13) follows at 22.43 SCY (25.60 projected), with a last-season LCM reference of 26.42. Asher Song (14) rounds out the group at 22.50 SCY (25.68 projected) with no last-season LCM reference available.

Liu-Tchorbadjiyski's 26.26 last-season LCM time and 25.39 projection put this event on the genuine watch list. A 1-second gap in the 50 fly at 14 is real, but his projection and development arc make this the most plausible record threat on the boys side.

100 Butterfly — NAG: 53.27 | Thomas Heilman (2021)

Elliot Leasure leads at 49.42 SCY (56.26 projected), with a last-season LCM reference of 59.40 — 6+ seconds above the record in actual competition. Ayden Tan (13) follows at 49.66 SCY (56.52 projected), with a 59.71 last-season LCM reference nearly identical to Leasure's. Jude Burkhart rounds out the group at 49.92 SCY (56.81 projected), with a last-season LCM reference of 58.48 — the most advanced real 100 fly LCM time in this group.

Heilman's record has clear protection — last-season LCM references in the 58–59 range put the field 5–6 seconds back. Burkhart's 58.48 leads on real performance, but the record isn't under pressure this cycle.

200 Butterfly — NAG: 1:59.02 | Michael Phelps (2000)

The most historically significant record in this dataset — set in 2000 and untouched for 26 years. Elliot Leasure projects to 2:01.97 — 2.95 seconds and 2.48% above the record. His last-season LCM reference of 2:08.18 shows he was 9+ seconds above the mark in real competition last summer. Steven Zhou-He (14) follows at 2:05.82 projected, with a last-season LCM reference of 2:11.09. Lubo Liu-Tchorbadjiyski rounds out the group at 2:06.91 projected, with a 2:18.84 last-season LCM reference — notably behind the other two in real long course form.

Phelps's 2000 record is well protected at every level — projections and last-season LCM references both confirm the distance. Leasure's development in this event is worth tracking on a multi-season horizon, but 2026 is not the year.

Individual Medley

200 IM — NAG: 2:03.73 | Shareef Elaydi (2024)

A fresh 2024 record. Ayden Tan (13) leads at 1:50.02 SCY (2:05.32 projected) — 1.59 seconds and 1.29% above the record on paper. His last-season LCM reference of 2:12.80 — set as a 12-year-old, when it stood as the 11-12 NAG — provides context: he's been competitive in LCM IM since he was younger, and now enters the 13-14 age group with another full summer ahead. Elliot Leasure follows at 1:51.19 SCY (2:06.62 projected), with a last-season LCM reference of 2:12.73 — almost identical to Tan's real baseline. Hanz Palattao is third at 1:52.35 SCY (2:07.91 projected), with a 2:13.64 last-season LCM reference.

Tan at 13 projecting to 2:05.32 is notable, but his last-season LCM reference of 2:12.80 — 9 seconds above the record — is the honest measure of where he currently stands in long course. The record is protected for now; Tan is the name to track as the season develops.

400 IM — NAG: 4:24.20 | Luka Mijatovic (2024)

Elliot Leasure leads at 3:55.36 SCY (4:27.65 projected) — 3.45 seconds and 1.31% above the record on paper — with a last-season LCM reference of 4:46.11, over 21 seconds above the mark in actual competition. Jude Burkhart follows at 3:57.09 SCY (4:29.57 projected), with a notably more developed last-season LCM reference of 4:39.15 — 15 seconds above the record in real competition, and the most relevant real benchmark in this event. Declan McDonald rounds out the group at 3:57.54 SCY (4:30.07 projected), with a last-season LCM reference of 4:53.93 from an April time trial.

Burkhart's 4:39.15 last-season LCM time is the most credible real data point in this event — he's been the closest to Mijatovic's record in actual competition. The record still has clear protection, but Burkhart is the swimmer applying the most real pressure.

The Bigger Picture

Two swimmers define the narrative of the Boys 13-14 LCM field this cycle, and both have a consistent theme: exceptional SCY speed paired with a long course conversion gap that the summer will begin to test.

Elliot Leasure (14) leads or finishes near the top of every backstroke, butterfly, and IM event in this dataset. His projections in the 100 and 200 back are both mathematically under standing records, but his last-season LCM references in those events tell a more measured story — 1.42 seconds above the 100 back record, and 7+ seconds above the 200 back. The consistent theme is a swimmer with short course performance well ahead of his long course results so far. He has one more summer as a 14-year-old, and the 100 back is the event most worth watching given how close his last-season LCM time already was.

Ayden Tan (13) appears in six events as a 13-year-old — 100 free, 50 and 200 back, 50 and 100 fly, and 200 IM — all while projecting competitively within the 13-14 age group. His last-season LCM references were set at 12, meaning every reference in this dataset was from a younger age group. He has two full summers remaining, and the 200 IM is the event where his trajectory is most interesting to follow.

Beyond those two: Lubo Liu-Tchorbadjiyski is the 50 fly and sprint story — his 26.26 last-season LCM reference in the 50 fly makes that the most credible near-term record threat on the boys side. Jude Burkhart owns the distance and IM real-performance picture, with last-season LCM times that lead the field in the 200 free, 800 free, 100 fly, and 400 IM. And Landon Williams in the 50 breast, whose last-season LCM time outpaced his own projection, is a small but telling sign of efficient long course breaststroke form.

All projections use classical SCY-to-LCM conversion. Converted times are estimates only. Last-season LCM reference times are from the 2024–25 season. Age eligibility based on August 1, 2026 cutoff (swimmer remains 13 or 14 as of 8/1/2026).
