Consistent Pace with Minor Setbacks Patrick Mattson demonstrated steady pacing throughout the 2025 Boulderthon 10K. His most efficient segment was between miles 1 and 2, improving from a 9:33 to a 9:08 min/mile pace. This adjustment strengthened his position initially but was followed by a gradual slowdown in the latter half. Early splits reflected controlled execution, with miles 1 to 3 executed under a 9:30 min/mile pace. The finish line time was recorded at 1:00:59, with an average pace of 9:50 min/mile across 6.2 miles. Compared to the 2024 Boulderthon, where he completed in 58:53, this year's elapsed time showed a slight increase. Focusing on maintaining the early mile speed in later segments can maximize race efficiency. The data indicates that strategic pacing adjustments could enhance future performance, particularly in the final miles. A commendable effort, placing 11th in the M60-64 division, showing consistent participation and competitiveness in a larger, 2428-participant field.
