Date: Sept. 27, 2026 Participant: Jenna Calabrese #32730 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Early Miles Anchor a Strong 10K Finish Jenna Calabrese completed the 2026 Boulderthon 10K in 1:01:49, an overall pace of 9:58 per mile, out of a field of 3,071. Calabrese opened fast, covering her first two miles in 9:10 and 9:03, before settling into a steadier rhythm through the middle miles. Mile three through five held between 9:50 and 10:15, showing a controlled pace shift rather than a sharp drop-off. The closing mile eased further, bringing her cumulative pace to just under 10:00 per mile by the finish. Given the opening pace, that first mile stands as her strongest sustained stretch of the day. Boulder's elevation, over 5,000 feet, adds context to the effort behind that early speed.
