Date: Sept. 27, 2026 Participant: Jason Sze #31321 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Through Five Miles Before a Late Fade Jason Sze crossed the 10K finish in 1:01:59. His opening mile came in at 10:05, but he settled into a strong rhythm through the middle miles, dropping to 9:44, 9:48, 9:40, and a race-best 9:24 for mile five his fastest mile of the day. That stretch pulled his cumulative pace down to 9:43 per mile by the five-mile mark, the tightest and quickest window of his race. The final mile slowed to 11:12, nudging his overall elapsed pace to 9:59 per mile. Running at Boulder's altitude of over 5,000 feet, Sze's build through the middle miles stands out as the strongest phase of his race. With that final-mile pace as the only soft spot, dialing in the closing stretch could be a worthwhile focus for next time.
