B.A.A. 10K M15-19: Isaias dominates in the Boston heat

• Albert Isaias won the M15-19 age group in 33:34 — a 5:24/mi pace that put nearly 3:32 of daylight between him and runner-up Dillon Salvin.
• Thomas Flaig, just 16, claimed 3rd in 37:23 — the youngest finisher on the podium, edging Salvin by only 17 seconds.
• Ryan Markey and Julian Hughes finished 9th and 10th in identical displayed times of 42:03 — the places confirm Markey edged ahead by the slimmest of margins.
• Sam Gustat (15) and Julian Hughes (16) were the youngest in the top 10, showing the M15-19 field had genuine depth across the full age range.

With 85°F on the thermometer and Boston's summer humidity pressing down, 91 teenagers still toed the line for the B.A.A. 10K — and Albert Isaias, 19, of Lowell, made it look like a different race entirely. His 33:34 was not just a win; it was a statement. Running 5:24 per mile through the heat, Isaias held his position steadily through the race, ultimately finishing 35th among the men — a result that speaks to how far ahead of his age-group peers he was running.

Dillon Salvin of Dover made a strong push in the middle miles, moving from 95th to 81st among the men between the start and 5K, but his 37:06 left him well behind Isaias at the line. Thomas Flaig of Newton, just 16 years old, ran a composed 6:01/mi to claim 3rd in 37:23 — and his closing split on the 8K-to-finish segment ranked 83rd among the women's field, a useful marker of how solid his finishing kick was in the conditions.

Further back, the race got genuinely tight. Benjamin Tatham and Alexander Carpenter rounded out the top five, with Carpenter showing the strongest progression of anyone in that group — moving from 218th to 175th among the men across the race. The 9th- and 10th-place battle between Ryan Markey (Kensington, CT) and Julian Hughes (Framingham, MA) produced the afternoon's closest finish: both clocked 42:03 on the display, but the timing system separated them, with Markey taking 9th. In a race run under genuine summer stress, every second counted.
