Steady Progress with Mid-Race Improvements Justin's performance in the 2025 Boulderthon Half Marathon was consistent, maintaining an overall pace of 7:46 min/mile over the 13.1-mile course. Starting with an 8:17 min/mile pace during the first mile, he improved his pace significantly in subsequent miles. Notably, the fastest mile was at mile 10 with a split time of 7:32, showcasing an ability to accelerate mid-race. Justins overall time was 1:41:45, placing him 426th out of 6546 participants, and 51st in his age division. Comparing to his previous half-marathons, Justin displayed noteworthy improvement from his 2023 entry where he finished in 1:56:12, reducing his time by over 14 minutes.
