Steady Negative Split Carries Strong Finish Gabe Zwanziger completed the half marathon in 2:21:33, an average pace of 10:48 per mile across the 13.1-mile course. After an opening mile of 12:16, Zwanziger's cumulative pace tightened steadily, dropping under 11:00 by mile six and finishing at 10:48. His final mile, covered in 10:04, was his fastest of the race, closing strong through the last stretch after passing the lululemon Power-Up Zone near mile 9.5. That late surge came at altitude, with Boulder sitting more than 5,000 feet above sea level, making the sustained pace drop through the closing miles a solid finishing display.
