Consistent Start, Slower Finish Alex Barba from Broomfield, CO, completed the 2025 Boulderthon 10K in a time of 1:01:39, pacing at 9:56 min/mile. Her second split was the fastest at an 8:55 min/mile pace, a strong performance that led to an improvement in her division placement from 32nd to 31st. Throughout the race, there was a gradual increase in split times, with the final mile being the slowest at a 10:50 min/mile pace. Alex showed consistency in the first half but faced challenges in maintaining pace in the latter miles. This 10K result is a promising step forward compared to her previous half marathon in the 2023 Boulderthon, where she finished with a pace of 10:41 min/mile. In her division, Alex managed to stay consistent within the top finishers, starting in 32nd and finishing in 41st place. To enhance future performances, focusing on sustaining speed in the later miles could help maintain early momentum.
