Date: Sept. 27, 2026 Participant: Frankie O'Brien #40172 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Start Fades Late but Cracks Top 4% Frankie O'Brien crossed the 5K finish in 20:55, placing 97th overall out of 2,677 in the field and 73rd among men a result inside the top 10% of the field. He also finished 8th in the men's 20-24 division. O'Brien opened with a 6:09 first mile before surging to his fastest mile of the race, a 5:56 second mile, showing strong even-effort pacing through two-thirds of the course. The final mile slowed to 8:08, pulling his overall pace to 6:44 min/mile. Given the race sits at Boulder's altitude of over 5,000 feet, the early pacing reflects a well-managed opening effort. A more conservative start could help sustain that mid-race speed through the finish next time.
