Consistent Start, Challenging Finish Martin Calvillo completed the 2025 Boulderthon Marathon with a total time of 4:22:43, recording an average pace of 10:01 min/mile for the 26.2-mile course. Starting strong, he achieved his fastest mile in 7:20 at the 11th mile. Consistency was evident in the initial splits, maintaining an impressive pace between 8:14 and 8:30 mins/mile from mile 3 to 7. Martin's pacing demonstrated notable stability early in the race, which is a significant positive. As the race progressed, maintaining pace became more challenging, with the splits showing a gradual slowdown post-mile 13, reaching a 12:28 min/mile pace at mile 20. This indicates the need for improved endurance and stamina training in the later sections of long races. Despite the challenges, Martin improved his overall time compared to his previous year's performance of 4:43:02. Continuing to focus on endurance will further enhance Martins race results in the future.
