Date: Sept. 27, 2026 Participant: Peter Guatto #41851 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Middle Mile Fuels Solid 5K Finish Peter Guatto completed the 2026 Boulderthon 5K in 29:20, an average pace of 9:28 per mile. Guatto's race unfolded in three distinct phases: an opening mile of 9:46, a sharp drop to 7:50 for mile two, and a final mile that eased back to 10:45. That middle mile stood out as his fastest stretch of the race by a wide margin, showing a strong surge before settling in for the close. Racing in his home city of Boulder, which sits above 5,000 feet of elevation, Guatto navigated the field before finishing on the Pearl Street Mall in downtown Boulder. A more even pacing strategy across the three miles could help him carry that mile-two speed further into the finish next time.
