Date: Sept. 27, 2026 Participant: Kate Grossman #12820 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fades Late but Holds On for a Podium Finish Kate Grossman finished the marathon in 4:02:05, an average pace of 9:14 per mile, placing third in the F 15-19 division. Her race was built on a steady front half: the first 10 miles clicked by in 1:27:30, an 8:45 average, before the pace eased gradually through the middle miles. The closing stretch from mile 20 to 23 was her toughest, with per-mile splits stretching past 11:00, before she settled back into the 9:48-9:58 range to close out the final miles into downtown Boulder. Given Boulder's elevation above 5,000 feet, that steady effort through the marathon's early miles stands out as the strongest sustained running of her day.
