  • Stoklos posted the 2nd-fastest women's split on the 6M→8M segment, a stretch where she was already climbing through the overall women's standings.
  • Tiffany Chung held steady in 6th among women throughout the final miles, finishing 2nd in NB30-34 in 2:05:36 (9:35/mi).

Shay Stoklos, 31, from San Francisco, made this race her own from early on. Tracking her movement through the women's field tells the story: she entered the gun at 5th among women and kept climbing — 4th, then 3rd, then all the way to 2nd, where she locked in and held firm through the finish. That relentless forward progression was backed by real speed: her 6M→8M split ranked 2nd among all women in the race, a sign that she was still pressing hard well past the midpoint. Her 8:10/mi average over 13.1 miles in 59°F and 17 mph wind is the headline number of the NB30-34 field.

Tiffany Chung, 32, from Oakland, was the picture of consistency. She sat 7th among women from the very first checkpoint through most of the race, cracking into 6th only in the final stretch — a position she held at the line, finishing NB30-34 in 2:05:36 at 9:35/mi. Her strongest individual segment came between 8M and 10M, where she posted the 6th-fastest women's split in the field.

Charlie Su (2:44:03, 12:31/mi) rounded out the podium in 3rd, showing her best relative speed early — the 12th-fastest women's split on the 2M→4M segment. Ash Haller finished 4th in 2:59:19 (13:41/mi), also logging her best segment on that same 2M→4M stretch (14th-fastest among women). Kai Santiago closed out the five-woman NB30-34 field in 3:05:29 at 14:09/mi, her strongest relative moment coming on the 6M→8M segment with the 13th-fastest women's split.
