Standout Mid-Race Surge in Boulderthon David Diaz from New York delivered a strong performance in the 2025 Boulderthon Half Marathon, representing Team DDGR. Maintaining a consistent pace, David completed the 13.1-mile course with a finishing time of 2:41:30, averaging a pace of 12:19 min/mile. Notably, he showed a striking improvement at mile 5 with a remarkable split pace of 7:04 min/mile, significantly faster than his other splits. His placement in the M50-54 division saw him finishing 91st, amongst a large field of competitors totaling 6,546 participants. One area to focus on for future races could be consistency in pacing, as there were significant fluctuations in split times from mile to mile. Gradually building endurance to avoid slowing down in later miles, such as the 16:06 split at mile 10, could further enhance performance. Nonetheless, his resilience and standout mid-race surge indicate promising potential for future races.
