Steady Pacing Carries Denver Runner Into Top 10% Justin Ashley Calingasan finished the half marathon in 1:47:38, placing 649th overall and 480th among men out of the field of 7,223. His splits held in a tight band through the middle miles, with elapsed pace never straying far from 8:10 per mile, before a slight settle over the closing miles to the finish. His strongest stretch came from mile 6 to mile 7, split in 8:00 and 7:59, the fastest miles of his race. That push came right around the point where the course passes the lululemon Power-Up Zone near mile 9.5, giving him a boost before the final miles into downtown Boulder. Considering Boulder's elevation above 5,000 feet, holding pace that consistently across 13.1 miles was a well-managed effort worth building on.
