M40-44: Chelanga Runs Away With It at Boston

• Sam Chelanga wins the M40-44 age group in 2:14:59 (5:09/mi), more than 1:20 clear of runner-up Esteban Trujillo.
• Trujillo (2:16:19) and Ser-Od Bat-Ochir (2:16:41) separated by just 22 seconds for the podium's final two spots.
• Sean Swift (NJ) was the race's great mover in the age group, climbing from outside the top 150 men at the early checkpoints all the way to 5th in M40-44 by the finish.
• The top 4 all broke 2:18; a gap of nearly 5 minutes separates 4th from 5th.

Sam Chelanga ran a commanding wire-to-wire performance to claim the M40-44 title at Boston, crossing in 2:14:59 at 5:09/mi — a time that would turn heads in any field. He was tracking among the top 25 men in the race through the halfway mark before fading slightly in the back half, a natural consequence of racing at that kind of pace on Boston's punishing Newton hills. Still, no one in the 40-44 age group came close. His winning margin of 1 minute and 20 seconds over Esteban Trujillo was decisive.

Trujillo (2:16:19, 5:12/mi) and Ser-Od Bat-Ochir (2:16:41, 5:13/mi) waged the day's tightest battle for the podium. Trujillo showed particular strength in the middle miles — his 20K-to-half segment ranked 42nd-fastest among men in the field — while Bat-Ochir was sharp early, posting the 43rd-fastest men's split from 5K to 10K. In the end, just 22 seconds covered them at the line. Tiidrek Nurme ran a composed 2:17:22 to claim 4th, finishing with the 47th-fastest men's split on the final stretch from 25.2 miles to the finish.

The most dramatic journey of the day belonged to Sean Swift of New Jersey. Running 5:27/mi, Swift was buried in the 160s among men at the early checkpoints but kept picking off competitors through the second half, ultimately landing 5th in M40-44 at 2:22:57. His 24M-to-40K split ranked 46th-fastest among men in the field — a reminder that Boston rewards those who hold back early. The gap between Swift and Nurme in 4th was nearly five minutes, underscoring just how elite the top tier of the M40-44 field was on a cool, overcast Patriot's Day in Boston.
