Jed Smith Half Marathon: Geneva Jerwers Owns the F1-29 Field

• Geneva Jerwers, 13, finished the only entrant in the F1-29 age group, completing the half marathon in 2:12:20 at a 10:06/mi pace.
• Her Out & Back→Lap 1 split ranked 14th-fastest among all women on that segment.
• She held her position among the women's field through the early miles before settling back as the race wore on.

Geneva Jerwers came to Sacramento and did exactly what was asked of her: she ran 13.1 miles through a cold, foggy morning — 50°F and 93% humidity — and crossed the finish line. At just 13 years old, she was the sole representative of the F1-29 age group, making her both the winner and the standard-setter for her peers at this year's Jed Smith Ultra Classic.

Her 2:12:20 finish, at a 10:06 per mile clip, tells the story of a young runner who kept moving when the fog and damp had every reason to slow her down. Among the women's field, she moved through the checkpoints — sitting 8th, then 11th, then 17th as the race progressed — a natural drift back as more experienced runners found their rhythm in the later miles.

The one bright spot in the splits data: on the Out & Back→Lap 1 segment, Jerwers posted the 14th-fastest women's split in the field. For a 13-year-old running her pace, that's a meaningful number — it suggests she went out with genuine energy on that stretch, holding her own against women across every age group. The back half is where the race had its say, but the early effort was real.

With no one else in her age group to measure against, the story here is simply a teenager finishing a half marathon on a grey January morning in Sacramento. That's worth noting on its own terms.
