B.A.A. 10K Women's 35–39: Omberg Owns It

• Katie Omberg, 35, finished in 1:03:58 — the sole finisher in the women's 35–39 age group.
• Moved from 6th to 4th among women between the opening 5K and the 8K mark — and held that position to the line.
• 2nd-fastest women's split on the 5K–8K stretch — the race's decisive middle segment was her strongest.

Katie Omberg had the women's 35–39 age group entirely to herself on a warm Boston morning — 77°F, 12 mph wind, and 31% humidity making every mile feel a little heavier than the clock suggests. She crossed in 1:03:58, running 10:18 per mile, and made the race her own not just by showing up but by racing it.

The story here is in the splits. Through the first 5K, Omberg sat 6th among the women. By the 8K mark she had climbed to 4th — a move powered by the 2nd-fastest women's split on that 5K–8K segment. In a race where the heat was a genuine factor, surging through the middle miles rather than fading takes real conviction, and the numbers back it up.

She held 4th among women from the 8K to the finish, crossing in 1:03:58 and locking in the women's 35–39 title as the only finisher in her age group. In a field thinned by the conditions, Omberg ran a complete race — patient early, aggressive in the middle, and steady when it mattered most.
