Strong Start Gives Way to a Gritty Second Half Carter Miller completed the marathon in 4:24:01, an average pace of 10:04 per mile across the 26.2-mile course. Miller's fastest stretch came in the opening six miles, covered in 54:23 for a 9:04 average pace, before the pace gradually eased through the middle miles. By mile 17 his cumulative pace had slipped past 9:30, and it continued to loosen through the low-to-mid 11:00s per mile from miles 17 through 23 including an 11:13 mile 22, near where the course passes the lululemon Power-Up Zone at roughly mile 22.5. Miller found another gear late, closing with a 10:04 final mile, tightening his overall pace back down after the tough middle stretch. The effort came at Boulder's altitude of over 5,000 feet, adding to the demands of the closing miles into the Pearl Street Mall finish.
