Boston M45-49: Lawrence Leads Wire to Wire in 2:27:04

• Steven Lawrence (MI) won the M45-49 group in 2:27:04 (5:37/mi) — more than five minutes clear of runner-up Edward Baker.
• Sam Ives (MN) posted the most dramatic charge of the day, climbing from 542nd to 171st among men between the start and the finish line.
• Ryan Bullock (UT) and Songming Syu finished back-to-back in 11th and 12th, both clocking 2:40:39 and 2:40:40 — separated by a single second across 26.2 miles.
• A field of 2,218 finishers made M45-49 one of the deepest age groups on the Hopkinton-to-Copley Square course.

Steven Lawrence put together one of the most commanding performances in the M45-49 group at the 128th Boston Marathon, crossing in 2:27:04 at a 5:37/mi clip. He held a steady position among the men's field throughout — sitting around 53rd to 65th in the men's standings across the middle miles — before tightening things up over the Newton Hills and closing with the 63rd-fastest split among women on the final stretch from 25.2 miles to the finish. That closing kick underscored just how controlled his effort was: he had enough left to accelerate when it counted.

Edward Baker (MA) was the story of the front half, surging from 233rd among men at the early checkpoint all the way to 136th by mile 20 before fading slightly to finish 2nd in 2:32:18 (5:49/mi). Juan Carlos Cardona rounded out the podium in 2:33:06, and Sam Ives (MN) delivered the day's most eye-catching trajectory — entering the top 200 men only after the 40K mark and charging to 4th in 2:33:51 on the strength of the 32nd-fastest split among women on that 40K-to-25.2M segment. Wayne Blas (KY) completed the top five in 2:35:07.

The middle of the M45-49 leaderboard was a gauntlet of sub-2:40 runners. Nicholas Thompson (NY) and Bryan Rusche (ON) finished 7th and 8th in 2:38:00 and 2:38:05 — five seconds apart — while Brian Martin (IL) and Javier Moro followed in 9th and 10th. The top 20 were all home by 2:42:35, with Gustavo Campiz (NY) and Gabriel Hernández Díaz sharing that mark to close out the listed finishers.
