Steady Split Splitting: A Consistent 8:20s Pace Through Boulder Luke Osborne covered the half marathon in 1:50:29, holding an 8:26 min/mile pace across the Boulder course. His cumulative pace stayed remarkably tight through the first six miles, ranging from 8:14 to 8:24 per mile, before a modest dip between miles 7-9 (8:35-8:50) as fatigue crept in. He closed strong, trimming his splits back to the 8:19-8:37 range over the final four miles to finish with his cumulative pace unchanged at 8:25. His fastest mile-plus stretch came early: miles 1 through 6 averaged 8:14 per mile, the most efficient running of his race. Miles 9 and 10, run around the lululemon Power-Up Zone near mile 9.5, held at 8:23-8:24, showing solid control through that section of the course before the finish on the Pearl Street Mall, all completed at Boulder's 5,000-plus-foot elevation.
