Steady Progression with Notable Consistency Tony Chang's race in the 2025 Boulderthon reveals a solid pace and performance consistency. Averaging an 11:49 min/mile pace, his race completion time was 2:34:48 for the half marathon. Starting strong with a 10:33 pace in the first mile, Tony maintained his rhythm, clocking mile times consistently between 10:35 and 11:46 for most splits. Notably, his 12th mile was a standout, recorded at 10:57, the second-fastest split of the race. One suggestion for future improvement is to address the pace variability in the middle and later stages of the race, particularly from miles 5 to 10, where the split pace varied from 11:15 to 14:15 min/mile. Maintaining an even pace throughout could enhance finishing times. Overall, Tony held a respectable position, placing 61st in the M55-59 division, amidst 6,546 participants, demonstrating his ability as a consistent competitor for Trottin Oxen.
