Strong Front Half Fuels Top-4% Marathon Finish Justin Laper finished the marathon in 3:34:21, placing 130th overall and 114th among men out of the field of 3,305. Through the first 12 miles he ran a steady 7:28 average pace, holding between 7:03 and 7:37 per mile, before easing through the second half as splits climbed into the 8:159:36 range. Cumulative pace stayed under 7:30/mile through mile 12, then drifted to 8:11/mile by the finish. His opening 12 miles stand out as the strongest stretch of the race, consistently faster than 7:30 pace despite Boulder's elevation above 5,000 feet. The closing miles, particularly 19 through 24, showed the steepest pace shift, yet he still finished well inside the top 10% of the field a result to build from for future marathon efforts.
