Date: Sept. 27, 2026 Participant: Agnieszka Socha #10274 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Pacing Through Halfway, Then a Late Test Agnieszka Socha finished the marathon in 4:07:38, an average pace of 9:27 per mile across the 26.2-mile course. Her early and middle miles were remarkably even, holding between 9:11 and 9:30 per mile from mile 1 through mile 18, with a standout mile 11 covered in 8:43 her fastest of the race. That consistency carried her cumulative pace to 9:16 per mile at the halfway point. Miles 21 through 23 brought a tougher stretch, with splits slowing into the 9:5910:40 range, before she rallied over the final three miles, closing with a 9:16 split into downtown Boulder. Given Boulder's elevation above 5,000 feet, that late finishing push stands out as a strong close to a well-paced effort.
