Chicago 13.1 Half Marathon: Evance Stalley Dominates the F50-54 Field

• Stalley wins by 7:40, finishing in 1:30:19 (6:53/mi) — the largest gap to 2nd place in the top-5 and a commanding margin in a 371-runner field.
• Irma Montes made the biggest move of the race, climbing from 352nd among women at the 5K mark all the way to 207th by the finish — the most dramatic upward surge in the top-5.
• Jennifer Govostis posted the strongest closing surge among the podium, recording the 101st-fastest women's split from 10K to 15K and climbing from 182nd to 123rd among women through that stretch before settling into 3rd.
• Renee Sexton and Christine Byers finished just 6 seconds apart (1:48:31 vs. 1:48:37) for 8th and 9th, the tightest battle in the listed results.

Evance Stalley made the F50-54 race her own from the start. Running 6:53 per mile through Chicago's streets on a crisp, clear morning, she moved from 60th among women at the 5K checkpoint up to 40th by the finish — a steady, relentless climb that left the rest of her age group well behind. Her 32nd-fastest women's split from 15K to the finish confirmed she wasn't just coasting to a win; she was still accelerating when it mattered most.

Behind Stalley, Suzanne Rinehart claimed 2nd in 1:37:59, holding relatively steady through the middle miles. Rinehart's strongest segment came between 8K and 10K, where she posted the 99th-fastest women's split in the field, but she gave back some ground late, sliding from 99th among women to 109th by the finish. Jennifer Govostis in 3rd told a different story — she was 182nd among women at 5K and kept climbing all the way to 123rd by 15K before finishing in 1:39:15, a composed and progressive effort.

The most entertaining subplot of the day belonged to Irma Montes. Starting conservatively — 352nd among women through the first 5K — she spent the entire race reeling in competitors, ultimately landing 5th in F50-54 at 1:42:36. Darla Erman, 4th in 1:42:05, ran the more measured race between them, though Montes's second-half charge made it close. Down the leaderboard, the battle for 8th and 9th between Renee Sexton (1:48:31) and Christine Byers (1:48:37) was decided by just six seconds across 13.1 miles — the kind of margin that keeps runners chasing finish-line clocks all the way to the tape.
