Steady Pace With a Strong Fifth-Mile Surge Stephanie Vandenberg completed the 10K in 58:29, an average pace of 9:26 per mile. Her splits held in a tight band through the race, opening with a 9:33 first mile and settling into the 9:069:28 range through the middle miles before a final-mile pace of 10:12. Her standout stretch came in mile five, covered in 8:58, the fastest mile of her race, pulling her cumulative pace down to 9:16 before the finish.
