Date: Sept. 27, 2026 Participant: Zoe Sullivan #12393 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fast First Half Gives Way to a Hard-Fought Finish Zoe Sullivan completed the 2026 Boulderthon Marathon in 4:05:49, an average pace of 9:22 per mile. She went out briskly, covering the first three miles in 25:11 (8:23/mile pace), and held mid-8:00s pacing through the middle miles. Miles 9 through 11 were a highlight, clicking off at roughly 8:12 per mile as she pushed back after a brief dip near mile 8. The back half proved tougher: miles 1920 and 22 slowed into the 11:3012:30 range before she rallied over the final mile, closing in 9:02. Boulder sits above 5,000 feet, a backdrop to any marathon effort here. Sullivan's early pacing showed strong control, and her late recovery in the closing mile reflects solid composure after a demanding middle stretch. A touch more even pacing through miles 1922 could help smooth out the overall effort next time.
