Negative Split Powers a 37-Second PR Phil Dumontet ran a smart, escalating half marathon, closing in 1:23:47 (6:23/mile) to finish 64th overall and 9th in the M35-39 division among 7,045 participants. His pace tightened steadily through the race, dropping from the mid-6:30s in the opening miles to a string of sub-6:10 splits between miles 10 and 13, including a 5:42 mile 11.9 and 4:35 mile 13. That surge lines up with the lululemon Power-Up Zone near mile 9.5, where he jumped from 77th to 63rd overall in a single split. Compared to his 2023 Boulderthon half (1:24:24), Phil trimmed 37 seconds despite a deeper field. The early milesparticularly a 7:38 split at mile 0.8 and 7:16 at mile 8stood out as his slowest stretches; tightening that opening rhythm could help him carry his strong closing pace over more of the course before the Pearl Street Mall finish.
