F30-34: Mary Reiser Runs Down the Field to Win in 2:49:37

• Reiser wins with a closing surge — her 4th-fastest women's split on the second half erased a mid-race deficit and delivered the F30-34 title in 2:49:37 (6:28/mi).
• Shannon's early speed couldn't hold — the 3rd-fastest women's split on the 5K→10K segment got Alexandra Shannon to 3rd among women by 10K, but she faded to finish 2nd in F30-34 at 2:54:43 (6:40/mi), 5:06 back.
• A tight cluster at the line — places 8 and 9 both clocked 3:10:45 and 3:10:56, separated by just 11 seconds; places 16 and 17 were even tighter, with Sydney Sumner (3:16:31) and Kimberly Greenberg (3:16:37) just six seconds apart.
• 812 finishers made F30-34 one of the deepest fields of the day at The People's Marathon.

Mary Reiser came to Arlington with a patient plan and the legs to execute it. Starting conservatively — she was sitting 9th among women through the middle stretch — Reiser began working her way forward in the second half, eventually posting the 4th-fastest women's split from the halfway point to the finish. By the time the monuments of Washington came into view, she had moved from 9th to 4th among women and locked up the F30-34 title in 2:49:37, averaging a crisp 6:28 per mile.

Alexandra Shannon ran the opposite race. Out of Encinitas, CA, Shannon fired one of the fastest early splits in the women's field — 3rd-fastest on the 5K→10K stretch — and was sitting as high as 3rd among women at 10K. But that early investment came at a cost. She drifted back through the second half, ultimately crossing in 2:54:43 (6:40/mi) for 2nd in F30-34, 5:06 behind Reiser. Mollie Geyer of San Diego also ran a strong early 5K→10K segment (12th-fastest among women) and held steady throughout, finishing 3rd in 2:57:09 (6:45/mi).

Behind the podium, the race offered its own drama. Katie Synge-Curtis, representing Devon, clocked the 21st-fastest women's split on the 21K→25K segment but couldn't quite bridge the gap to the top three, finishing 4th in 3:04:25 (7:02/mi). Jordan Grande of Tucson rounded out the top five in 3:08:01 (7:10/mi), with her best relative effort coming on the 15K→21K stretch. The field behind them was dense and competitive — five finishers between 7th and 11th place were separated by fewer than 90 seconds — fitting for a race of this scale, winding past the national monuments under a cool 43°F morning sky.
