Date: Sept. 27, 2026 Participant: Charles Thibou #30279 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Effort Through Boulder's 10K with a Strong Fifth-Mile Surge Charles Thibou, 57, of Colorado Springs, finished the 2026 Boulderthon 10K in 1:33:31, an overall pace of 15:05 per mile. His race unfolded steadily, with early miles settling around 15:20-15:47 pace before a clear shift in the second half. Splits held close to that range through mile four, then he found his best rhythm in mile five, covering it in 13:40 his fastest mile of the race before easing slightly in the closing mile. The race took place in Boulder, Colorado, which sits above 5,000 feet of elevation, adding context to the effort across the distance. Thibou's ability to accelerate midrace, rather than fade, stands out as the highlight of his day a pattern worth building on if he returns to chase an even stronger closing mile next time.
