Negative Splits Carry Steady Finish Ernesto Herrera covered the half marathon in 1:38:09, an average pace of 7:29 per mile. The race built steadily: after an 8:24 opening mile, Herrera settled into the low-to-mid 7:00s through the middle miles before surging over the final five miles, covering that stretch miles 9 through 13 in roughly 7:03 per mile, his strongest sustained running of the day. That push included a 6:46 mile and a 6:54 closing mile, showing well-managed effort late in the race. Along that stretch, near mile 9.5, runners pass through the lululemon Power-Up Zone before making the turn back toward downtown Boulder, where the course finishes on the Pearl Street Mall at over 5,000 feet of elevation.
