Date: Sept. 27, 2026 Participant: Yonatan Rosen-Rager #24696 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Splits Carry Half Marathoner to a Consistent Finish Yonatan Rosen-Rager finished the Half Marathon in 2:01:44, an overall pace of 9:17 per mile. His mile-by-mile pacing stayed remarkably tight throughout, rarely drifting more than 20 seconds from his overall average, a sign of well-managed effort across the full 13.1 miles. The strongest stretch came late, as he clicked off mile 12 in 8:52, his fastest full mile of the day, before easing back to close things out. That surge came right around where the course passes the lululemon Power-Up Zone near mile 9.5, and he carried that composure to the finish on Pearl Street Mall in downtown Boulder, a fitting cap to a day raced at over 5,000 feet of elevation.
