Date: Sept. 27, 2026 Participant: Jonathan Yu #40821 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers a Steady 5K Finish Jonathan Yu completed the 2026 Boulderthon 5K in 27:30, averaging 8:52 per mile. His race unfolded in three distinct phases: an opening mile of 9:25, a sharp drop to 7:29 for mile two, and a final mile that eased back to 9:37. That middle mile stood out as his fastest stretch of the race, showing a strong surge before settling in for the close. Running at Boulder's elevation of over 5,000 feet, Yu's ability to find that gear midrace speaks well of his pacing instincts. A slightly more even split between the first and last miles could help him carry that middle-mile strength through to the finish in future 5Ks.
