Napa Valley Half Marathon: Karen Ostlund Owns the F80-99 Field

• Solo and certain: Ostlund was the only finisher in the F80-99 race, crossing in 3:17:17 at a 15:03/mi average pace.
• Conditions were real: 40°F, light rain, and 84% humidity made this a demanding morning for anyone on the course.
• Steady through the finish: Ostlund held her line across the second half, completing the 6.9M-to-Finish stretch to wrap up her race.

Karen Ostlund, 80, from Austin, TX, stepped to the line in Napa on a cold, wet March morning and did what no other woman in the F80-99 field did: she finished. In 3:17:17, at 15:03 per mile, she covered all 13.1 miles through the rain and came out the other side with a win that was entirely her own.

There's no one to compare her to within this field — she was it. But the conditions were shared by everyone on the course: 40°F, a persistent light rain, and humidity pressing at 84%. Getting to that finish line required the same roads, the same weather, and the same mileage as every other runner. Ostlund navigated it all and crossed.

She is the F80-99 champion of the 2024 Napa Valley Half Marathon, full stop. Sometimes the most straightforward story is also the one worth telling plainly.
