Date: Sept. 27, 2026 Participant: Adriana Vegas #21604 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Consistent Effort Secures Another Division Runner-Up Finish Adriana Vegas completed the 2026 Boulderthon Half Marathon in 1:41:55, placing second in the F45-49 division for a third consecutive year. Her time trails her 2024 result of 1:35:51 and her 2025 finish of 1:37:58, continuing a gradual year-over-year increase across her three Boulderthon half marathon appearances. Vegas opened strong, covering the first two miles in 14:37 a 7:18 per-mile pace that stood as her fastest sustained stretch of the day. From there, her per-mile splits eased steadily, settling into the high 7:00s and low 8:00s pace through the middle and late miles before crossing the line on the Pearl Street Mall. Boulder's elevation, over 5,000 feet, adds context to any pacing shift across the 13.1-mile course, which in 2026 featured close to 50% less net elevation gain than in prior years.
