Strong Opening Miles Give Way to a Hard-Fought Finish Colby Stockton completed the marathon in 4:21:42. His first eight miles ticked by between 7:42 and 8:04 per mile, the fastest sustained stretch of his race, and through mile 18 his cumulative pace held near 8:30. From there the effort cost him, with mile splits sliding past 12 and then 15 minutes through the low 20s before settling in over the final miles. Stockton's race unfolded at Boulder's altitude above 5,000 feet, on a course that runs out past Boulder Reservoir before returning to finish on the Pearl Street Mall. His toughest miles came right around the lululemon Power-Up Zone near mile 22.5, where his pace was at its slowest before he steadied to the line.
