Date: Sept. 27, 2026 Participant: Jillian Seitz #20267 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Start Fuels a Strong Half Marathon Finish Jillian Seitz completed the Half Marathon in 2:31:52, an 11:35 min/mile pace. Her opening two miles were the fastest stretch of the race, clocking a combined 10:23 min/mile pace before the effort settled into the 11:0012:00 min/mile range for the remainder of the course. That early rhythm gave her a cushion that carried through to a solid finish on the Pearl Street Mall. Boulder's elevation, over 5,000 feet, adds context to any pace run there, and Seitz's ability to hold her pace within a tight band over the second half of the race speaks to well-managed effort. Future efforts could look to sustain that early-mile rhythm a bit longer before settling into cruising pace.
