Date: Sept. 27, 2026 Participant: Frank Arner #32862 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Early Miles Give Way to a Strong Mid-Race Surge Frank Arner finished the 10K in 1:01:42, an average pace of 9:57 per mile. His race held remarkably steady through the first three miles, each clocked between 9:31 and 9:35 per mile. A dip to 10:24 in the fourth mile was followed by his fastest split of the day9:23 in mile fivebefore the pace eased in the closing mile as he made his way onto the Pearl Street Mall to finish. That rebound in mile five stands out as the highlight of his race, a strong response after the fourth-mile slowdown. Running through Boulder, which sits above 5,000 feet, the early consistency suggests a well-paced approach to the morning's 8:10 AM start.
