Girls U-10 at the Shamrock 8K: Guerrero and Primmer in a Dead-Even Finish, Langley Steals the Show

By MyRace AIMarch 21, 2026
  • Isabella Guerrero (1st, 1:05:37) and Bella Primmer (2nd, 1:05:37) crossed the line in the same clock time, but Guerrero edged ahead by the finest of margins to claim the top spot among the U-10 girls.
  • Hannah Langley (3rd, 59:45) ran the fastest time in the field at 12:01/mi — a full 5:52 quicker than the winner's time — yet finished 3rd by division place.
  • Savannah Miley (11th, 55:24) posted the single fastest finish time of any named finisher in the U-10 girls field, running 11:09/mi across 8K.
  • Taylor Epes (8th, 1:16:32) and Ariel Jones (16th, 1:15:23) each pulled double duty at the Shamrock weekend — Epes finished 10th among women in the 1M, Jones 7th among women in the 1M — before lining up for the 8K.

The U-10 girls field of 39 at the Shamrock 8K delivered one of the most intriguing finishes of the morning. Isabella Guerrero and Bella Primmer — both age 10, both running 13:12/mi — hit the tape in an identical displayed time of 1:05:37, but the timing system separated them by the slimmest possible margin, with Guerrero taking 1st and Primmer 2nd. Their mid-race movement tells a similar story too: both climbed steadily through the women's field from roughly the same position at the 2M mark, with Primmer actually posting the 267th-fastest women's split on the 2M-to-4M stretch — two spots quicker than Guerrero's 269th — yet Guerrero held on for the win. It was a genuine catch-up that Primmer nearly completed.

Meanwhile, Hannah Langley ran a different race entirely. The Charlottesville 10-year-old came through the early miles in a more conservative position — 822nd among women at the 4M mark — before unleashing the 248th-fastest women's split on the 4M-to-Finish stretch to surge home in 59:45. That's the fastest finish time of any of the top-10 named finishers, yet the division standings placed her 3rd. The numbers are not contradictory; they simply reflect how the early miles unfolded. Langley ran the back half fastest among this group and finished with the quickest time on the board for a top-10 finisher — a strong closer's performance at 12:01/mi.

The depth of the field adds more texture. Savannah Miley, finishing 11th in the division at 55:24 and 11:09/mi, posted the fastest raw time among all named finishers — a remarkable number for any runner, let alone one in the U-10 field. And for sheer weekend ambition, Ariel Jones and Taylor Epes deserve recognition: both competed in the 1M race (Jones 7th among women, Epes 10th among women) and then returned for the 8K. Across 39 finishers on a breezy 53°F Virginia Beach morning, the U-10 girls brought real racing to the Shamrock 8K.
