Chicago 13.1 Half Marathon: Guerrero takes the F60-64 crown in a dominant display

• Angelica Guerrero won the F60-64 age group in 1:46:04 (8:05/mi), finishing nearly a full minute clear of runner-up Libby Harvey-Hill.
• The gap from 2nd to 3rd was dramatic: Harvey-Hill's 1:47:02 sat more than 17 minutes ahead of Kayoko Hamamura's 2:04:31 in 3rd.
• Places 3 through 6 were tightly contested — just 2:13 separated Hamamura (2:04:31) from Deborah Shutter (2:06:44).
• A field of 77 finishers made this one of the deeper age-group contests of the morning.

Angelica Guerrero ran a wire-to-wire commanding race, holding a pace of 8:05 per mile across 13.1 miles to claim the F60-64 title. Her gender place did fluctuate through the middle miles — she moved from 231st among women at the 5K mark to 246th by the 15K — but she reeled in rivals in the closing stretch, finishing 240th among women before her final position of 299th reflects the late charge of runners around her. None of it mattered where it counted: in the F60-64 group, she was untouchable.

Right behind her, Libby Harvey-Hill ran a composed 8:10-per-mile effort to claim 2nd in 1:47:02. Harvey-Hill was moving well through the middle of the race, climbing from 308th to 294th among women between the 8K and 15K marks, with her strongest relative moment coming on the 8K–10K segment. The 58-second margin between her and Guerrero sounds close on paper, but in practice Guerrero was never seriously threatened.

The battle for the remainder of the podium told a different story entirely. Kayoko Hamamura (3rd, 2:04:31) and Susan Barry (4th, 2:05:59) were separated by just 88 seconds, with Irma Lagunes Perez (5th, 2:06:19) and Deborah Shutter (6th, 2:06:44) close enough to make that a genuine four-way contest for the final podium spot. Barry was a strong finisher, moving steadily from 1528th to 1330th among women through the 15K before settling back slightly. Perez, meanwhile, posted her best relative split on the closing 15K-to-finish leg, suggesting she had something left when it mattered most — just not quite enough to catch Barry.
