F35-39: Brittany Alvarez Dominates Chicago 13.1 with a 1:16:20

• Alvarez wins by 8:41 over runner-up Drusia Dickson — the largest margin on the F35-39 podium and one of the most commanding victories in the age group.
• Janessa Juarez's late charge: she moved from 29th to 23rd among women in the final stretch, posting the 21st-fastest women's split on the 10K–15K segment to lock up 3rd in F35-39.
• Tina Muir's closing surge: starting the race 63rd among women, she reeled in 18 spots to finish 45th among women — the biggest mover in the top 20 of the age group.
• 636 finishers completed the F35-39 race, making it one of the deepest fields on the course.

Brittany Alvarez ran Chicago 13.1 at 5:49 per mile — a pace that put her 10th among all women by the finish — and she never let the race come to her. She entered the top 10 among women between 15K and the finish line, and her 8th-fastest women's split on the 10K–15K segment was the engine of that move. From gun to tape, this was a controlled, confident performance that left the rest of the F35-39 field well behind.

Drusia Dickson held 2nd in the age group throughout, running 1:25:01 at 6:29 per mile and climbing to 18th among women by the finish. Her 18th-fastest women's split on the 5K–8K segment showed she had genuine pace in the early middle miles. Janessa Juarez ran 1:26:15 to claim 3rd, steadily working through the women's field across every checkpoint — a patient, progressive race that paid off.

The story deeper in the standings belonged to Tina Muir of Saint Louis. Sitting 63rd among women at 5K, she ground her way to 45th by the finish, posting the 37th-fastest women's split on the 15K-to-finish segment. It wasn't enough to crack the top four in F35-39, but it was the most visible momentum swing in the group. Behind her, places 6 through 17 were separated by just six minutes — a dense, competitive pack that made every second matter on Chicago's flat, fast streets.
