Strong Start with Gradual Slowdown Sumin Song participated in the 2025 Boulderthon 10K with a final time of 56:18 and an average pace of 9:04 min/mile. Starting off strong, Sumin maintained a sub-9 minute pace for the first three miles. Notably, the second mile was his fastest at 8:11 min/mile, highlighting a consistent rhythm early on. As the race progressed, there was a slight deceleration evident from split times that increased to 9:36 min/mile by the fourth mile. Sumin finished 257th out of all male participants and 58th in his M30-34 age division. To improve, focusing on maintaining the momentum from the initial miles throughout the entire race might be beneficial. Joining the "Are We There Yet" team seemed to add a supportive atmosphere worth leveraging for future races.
