Date: Sept. 27, 2026 Participant: Rebekah Zullo #21143 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Fuels Steady Half-Marathon Effort Rebekah Zullo finished the 2026 Boulderthon Half Marathon in 2:05:20, an overall pace of 9:34 per mile. Her race built steadily from a brisk opening, with cumulative pace sitting at 8:21 through the first mile and gradually easing to 9:33 by the finish - a classic positive split as the back half asked more of her legs. Her strongest sustained stretch came early: miles one through five clicked off at an 8:50 average pace, the fastest mile-plus segment of her day. Zullo's race carried her past the lululemon Power-Up Zone around mile 9.5, a stretch she covered in the 9:51-9:52 range, before the final miles softened into the 10:00s on her way into downtown Boulder. Finishing on the Pearl Street Mall at over 5,000 feet of elevation, her early pace stands out as the foundation of the effort - a small pacing reserve for the closing miles could keep that opening speed alive longer next time.
