Date: Sept. 27, 2026 Participant: Joanna Zemek #40128 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Powers Steady 5K Finish Joanna Zemek completed the 2026 Boulderthon 5K in 31:32, an overall pace of 10:10 per mile. Her race unfolded in three distinct phases: an opening mile at 10:33, a strong surge to 8:45 through mile two, and a settling third mile at 11:12 to the finish. That middle mile stood out as her fastest stretch of the race, a solid push through the field before easing back toward the Pearl Street Mall finish. Racing at altitude in Boulder, sitting over 5,000 feet, adds its own demand to any pace, and Zemek's ability to find a gear in the second mile speaks well of her effort. A more even split between miles two and three could be a useful focus for her next 5K.
