B.A.A. 10K F20-24: English Jackson Runs Away With It

• English Jackson wins in 36:57 (5:57/mi), finishing 16th among all women and posting the 13th-fastest women's split on the final 8K-to-finish stretch.
• Nearly a three-minute gap separates Jackson from runner-up Emilie Baxter (39:59), the widest margin between any two consecutive podium finishers.
• Baxter was the biggest mover on the day, climbing from 55th to 33rd among women across the three checkpoints to claim 2nd in the F20-24 age group.
• The top ten were tightly bunched behind the podium, with 4th-place Casey Nelson (40:54) through 10th-place Ann Byerley (41:56) separated by just over a minute across six runners.

English Jackson simply ran a different race than everyone else in the F20-24 field on a warm Boston morning — 77°F, breezy, and unforgiving for pace. Running at 5:57 per mile, she crossed in 36:57 and was already climbing the women's overall standings before most of her age-group peers had found their rhythm, moving from 19th to 16th among all women by the finish. That 13th-fastest women's split on the closing 8K-to-finish segment confirms she wasn't just surviving the heat — she was accelerating through it.

The battle for 2nd was the more dramatic story. Emilie Baxter of Brookline came in at 39:59 and earned her podium the hard way, surging from 55th among women at the 5K mark all the way to 33rd by the finish. Annika Hildebrandt of Cambridge took 3rd in 40:41, but her trajectory told the opposite tale — she moved from 37th to 41st among women in the back half, fading just enough for Baxter to put nearly 45 seconds of daylight between them.

Casey Nelson (4th, 40:54) and Heidi Santa Cruz (5th, 41:16) both held relatively steady positions in the women's field throughout, neither gaining nor losing significant ground after the midpoint. Behind them, Annie Glodek (6th, 41:26), Molly Oconnor (7th, 41:31), Lauren Burgett (8th, 41:37), Shira Weiner (9th, 41:45), and Ann Byerley (10th, 41:56) completed a remarkably compact top ten — 90 seconds covering five finishers in a 300-person age group. In a race this deep and this warm, that kind of clustering makes every second count.
