Date: Sept. 27, 2026 Participant: Natasha Zacchio #12690 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fast Front Half Fuels Top-10% Marathon Finish Natasha Zacchio finished the 2026 Boulderthon Marathon in 3:54:17, placing 296th overall and 60th among women in a field of 3,305. Her race showed a clear two-phase shape: through the first 13 miles she held a brisk 8:01 min/mile pace, then eased into a steadier cruise over the back half as splits settled into the 9:4010:50 min/mile range from mile 19 onward, closing in 8:56 min/mile overall. Her sharpest mile came at mile 11, clocked at 7:42, the fastest of the race and a highlight of a strong opening effort. That early pace held up well given Boulder's elevation above 5,000 feet, and maintaining more of that rhythm into the middle miles could be a useful target for future long-distance efforts.
