Date: Sept. 27, 2026 Participant: Rebecca Alterman #32444 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Middle Miles Power a Steady 10K Finish Rebecca Alterman completed the 2026 Boulderthon 10K in 55:35, an 8:58 min/mile pace. Her race unfolded with remarkable consistency through the middle miles before a slightly slower final mile closed things out. Mile five stood out as her strongest stretch, clocked at 8:26, a notable pickup after a mile four dip to 9:09. That surge reflected a runner finding rhythm before the finish. Racing at Boulder's altitude of over 5,000 feet, Alterman's ability to hold sub-9:00 pace across four of six miles speaks to solid pacing discipline. She crossed the finish line on the historic Pearl Street Mall, capping a well-managed effort with room to build on that mile-five surge in future starts.
