Steady Early Pace Anchors a Strong Half Marathon Finish She finished the half marathon in 1:49:43, an 8:22 per mile pace. The opening four miles were her sharpest work, holding between 7:52 and 8:11, before a softer patch through miles 8 and 9 pushed the pace to 8:44 and 8:45. Mile 11 proved her toughest of the day at 9:55, but she answered with two solid closing miles at 8:31 and 8:28 to bring it home. Mile 4, at 7:52, stood out as her fastest of the race. That mid-race dip came right around the lululemon Power-Up Zone near mile 9.5, a notable marker on the half course before the final push into downtown Boulder. Racing at Boulder's altitude, over 5,000 feet, she still kept her overall pace within a tight band from start to finish.
