Consistent Pacing with Noteworthy Improvements Mid-Race Emily Lim maintained a consistent pace throughout the 2025 Boulderthon Half Marathon, completing the race in 1:44:05 with an average pace of 7:56 min/mile. Starting with a strong 7:58 min/mile pace for the first mile, she exhibited an impressive increase in speed, especially between miles 2 and 5, reaching a best split pace of 7:35 min/mile in her second mile. Her ability to sustain a relatively consistent pace is demonstrated by maintaining steady positioning, moving from 572nd overall at the first mile, climbing to as high as 442nd by the mile 7 marker. Interestingly, Emily's performance shone through mid-race, particularly between miles 3 to 6, showing splits consistently under or around 7:41 min/mile. A slight slowdown was noted in the latter part of the race, especially after mile 7. A review of the strategy towards the latter miles might unlock further potential for future races. Overall, Emily secured a respectable 25th place in her division among females aged 20-24.
