Consistent Pace with Strong Mid-Race Performance Tessa Kertzer from Boulder, CO, participated in the 2025 Boulderthon Half Marathon, finishing a 13.1-mile course in 1:42:01 with an average pace of 7:47 min/mile. Over the course of the race, Tessa maintained strong and consistent pacing, particularly excelling mid-race. Notably, she achieved her fastest split (7:26 min/mile) in the fifth mile, which significantly improved her overall rankings in both her gender and age division. Tessa's performance showed considerable strength in maintaining a solid pace across miles, thereby securing a respectable position. In particular, her efforts during the first half of the race helped her achieve an 8th place in her division during the fifth mile; this indicates potential for even stronger finishes. To enhance her performance further, she could explore strategies for maintaining a more even split time in later miles, as splits slightly slowed from mile eight onwards. Overall, an impressive showing in a large field of 6,546 runners.
