Date: Sept. 27, 2026 Participant: Josh Fiedler #27819 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Early Pace Fades Over Back Half of the Half Josh Fiedler finished the Half Marathon in 2:38:16, an average pace of 12:04 per mile. His race peaked early: after an opening mile of 11:41, he clicked off consecutive sub-10-minute miles through mile 4, reaching an elapsed pace of 10:25 min/mile at that point his strongest stretch of the day. From there, per-mile splits lengthened steadily, climbing from the 9:43 mile 4 split to a 14:46 closing mile, pushing his overall elapsed pace up nearly two minutes per mile by the finish. Boulder's elevation, sitting above 5,000 feet, adds a layer of difficulty to any pacing plan. Given the strong first quarter of this race, Fiedler might consider a slightly more conservative early pace next time to help sustain that rhythm through the closing miles.
