F30-34 at Chicago 13.1: Lagat Leads Wire to Wire

• Mercy Lagat won the F30-34 age group in 1:09:37 (5:19/mi), holding 2nd among all women from start to finish and posting the fastest women's split on the 8K→10K segment.
• Maggie Montoya closed in 1:09:52 — just 15 seconds back — after climbing from 4th to 3rd among women by the 5K mark and never looking back.
• The gap from 3rd to 5th was tight: Joyline Chemutai (1:11:28), Yuka Ando (1:12:21), and Molly Bookmyer (1:12:25) were separated by under a minute, with Ando edging Bookmyer by just four seconds at the line.
• Britney Romero and Vanessa Righeimer finished 11th and 12th in 1:26:14 and 1:26:15 — one second apart across 13.1 miles.

Mercy Lagat ran a controlled, authoritative race. She sat 2nd among all women at every checkpoint and never wavered, averaging 5:19 per mile across the full 13.1. Her sharpest moment came on the 8K→10K stretch, where she posted the fastest women's split of anyone in the field on that segment — a move that underscored she wasn't just hanging on to position, she was actively racing.

Maggie Montoya made the most compelling charge of the morning, moving up from 4th to 3rd among women before the 5K mark and sustaining that effort all the way to a 1:09:52 finish — good for 2nd in F30-34 and 3rd among all women. Her 3rd-fastest women's split on the 5K→8K segment was the engine of that move. Fifteen seconds is a slim margin over a half marathon, and Montoya made Lagat work for every one of them.

Behind the top two, the race for the podium and beyond was genuinely scrappy. Joyline Chemutai — also from Wailuku, HI, like Lagat — held 3rd in F30-34 in 1:11:28. Then came a fascinating four-second duel: Yuka Ando, who posted the 4th-fastest women's split on the closing 15K→Finish stretch, edged Columbus's Molly Bookmyer 1:12:21 to 1:12:25. Bookmyer had actually led Ando through the middle miles, sitting 5th among women while Ando was 6th — but Ando's strong finish flipped the result right at the tape.
