Balanced Pacing with Notable Split Variation Matthew completed the 2025 Boulderthon 10K in a time of 1:05:32, maintaining an overall pace of 10:34 min/mile. The race had a total of 2428 participants. His performance displayed varied pacing; the first mile was his fastest at 9:53 min/mile, while mile five was the slowest with a 11:52 min/mile pace. Despite these differences, he still managed a consistent effort across the course. His overall pace was slightly slower than some past marathon performances, where he has showcased sub-9:00 minute paces. For future races, aiming for more uniform pacing between splits could help improve overall time. As seen, the fifth mile was significantly slower than the initial pace, suggesting the need for strategic pacing to maintain energy. Practicing sustained speed training sessions could help enhance endurance and pacing stability. His strong start and impressive split consistency in previous marathons are promising aspects that could be harnessed in further events.
