Steady Early Pace Gives Way to a Tougher Back Half Jake Barfield completed the marathon in 4:08:17, an average pace of 9:28 per mile. His race split cleanly in two: the first half came through in about 1:56:48 (roughly 8:55 per mile), while the second half slowed to near 10:02 per mile as the closing miles wore on, with the largest dip between miles 20 and 25. The first ten miles were the most consistent stretch of the day, holding between 8:53 and 9:12 per mile without a single lapse outside that range. That composure set up the middle miles well before the pace gradually eased. Racing at Boulder's elevation of over 5,000 feet, Barfield covered the course's stretch out past Boulder Reservoir and the county backroads before finishing on the Pearl Street Mall. Building more strength for the final 10K could help carry that early rhythm further into the race next time.
