Steady Sub-6:10 Pace Powers a Top-Tier Half Caleb Clark finished the Boulderthon Half Marathon in 1:20:29, an average pace of 6:08 per mile, placing 41st overall and 35th among men in a field of 7,223. He crossed in 4th place in the Male 20-24 division. Clark's race was remarkably even, holding between 6:02 and 6:08 cumulative pace through the first ten miles before a brief dip to 6:33 in mile 11. His strongest single mile came early, a 5:52 split from mile 4 to 5, and he closed with a 6:10 final mile to seal the finish on the Pearl Street Mall. This consistency reflects well-managed effort across a distance that finishes in downtown Boulder, at over 5,000 feet of elevation.
