Consistent Pacing with Notable Mid-Race Surge Yuchen Zhou completed the 2025 Boulderthon Half Marathon with a consistent performance and a strong finish. Throughout the race, Yuchen maintained an average pace of 8:23 min/mile, finishing in 1:50:01. A noteworthy moment came after the fifth mile, where she significantly improved her pace, moving from 8:23 min/mile in mile 4 to 8:13 min/mile. This mid-race surge was paired with an impressive elevation in placements, climbing to 127th in her gender category and 20th in her division. Yuchen's race started with a steady pace of 7:53 min/mile, hitting the first mile strongly. While there was a gradual increase in split times from miles 6 to 11, she managed to maintain an efficient cadence across the whole event.
