Masters Men Chicago: Mansfield Runs Away with It

• David Mansfield won the Masters Men race in 2:18:29 (5:17/mi), finishing 13 minutes 13 seconds clear of runner-up Samuel Bradbury.
• Mansfield's closing stretch was electric: he posted the 31st-fastest men's split on the 40K-to-finish segment across the entire men's field — masters legs, world-class pace.
• The battle for 2nd through 12th was fierce: Bradbury (2:22:42) through Roman Fosti (2:29:38) covered just over seven minutes, with Stephen Jackson (2:29:33), Manuel Diaz (2:29:34), and Luke Baltrusch (2:29:37) separated by a mere four seconds across 8th, 9th, and 10th.
• A field of 14,666 Masters Men made this one of the deepest age-group competitions of the entire 48th edition of the Chicago Marathon.

David Mansfield of Clonmel arrived at the 48th Bank of America Chicago Marathon and made the Masters Men race his own from the opening miles. Running at 5:17 per mile across 26.2 miles in 54°F conditions, he crossed in 2:18:29 — a margin of victory so commanding that second place was never really in doubt. His gender place among the men's field told the story: he moved steadily from 42nd at the first checkpoint all the way to 34th among all men by the finish, a masters runner trading blows with the open field on the streets of Chicago's 29 neighborhoods.

Samuel Bradbury (Amherst) was the clear second-best master on the day, finishing in 2:22:42 at 5:27/mi. He was the one genuinely gaining ground late — his 37th-fastest men's split on the 40K-to-finish segment drove him from 57th to 55th among all men in the closing miles, a strong finish that locked up the runner-up spot. Markus Ploner of Bolzano rounded out the podium in 2:23:54 (5:29/mi), his best work coming mid-race: he posted the 46th-fastest men's split on the Half-to-25K segment in the whole field, moving from 72nd to 57th among men through that stretch before fading slightly to 68th at the tape.

Mustapha Lhamzi (Villeparisis) was the great mover of the top ten, climbing from 125th among men at the first checkpoint all the way to 93rd at the finish in 2:25:29, with the 45th-fastest men's split on the 40K-to-finish leg powering his late charge. James Mountford of Hastings made perhaps the boldest journey of anyone in the top five — starting 286th among men, he carved his way to 113th by the finish in 2:27:20, a sustained surge that earned him 5th in the Masters Men.

Then came the log-jam. Andrew Deak (2:28:15), William Navarre (2:28:39), and a cluster of eight runners between 2:29:33 and 2:29:40 — Jackson, Diaz, Baltrusch, Fosti, and De Vries among them — fought across 26.2 miles to land within a single minute of each other for places 6 through 12. In a field of 14,666, that kind of density at the sharp end is a testament to just how fast this masters cohort came to run on a cool Chicago morning.
