Date: Sept. 27, 2026 Participant: Isabella Bono #30982 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Through the Front Half Fuels Solid 10K Finish Isabella Bono covered the 2026 Boulderthon 10K in 54:27, an 8:46 min/mile pace. Her race built steadily off a strong start, holding 8:10 min/mile pace through the first two miles before easing slightly across the middle miles as cumulative pace crept toward 8:30 min/mile by mile five. That opening stretch miles one and two at 8:10 min/mile stood as the fastest sustained running of her race. She crossed the line on the Pearl Street Mall in downtown Boulder, a finish shared by every distance in the event, capping a run completed at over 5,000 feet of elevation.
