Steady Start Fuels a Gradual Fade Through the Back Half Carissa Blosser covered the Boulderthon half marathon in 2:20:15. She opened with her quickest mile of the day at 9:45, and held pace in the high 9:00s through the first five miles, reaching that point in 49:49. From there, per-mile splits eased steadily, settling into the 10:3011:30 range over the closing miles before crossing the finish on the Pearl Street Mall. Running at Boulder's altitude of over 5,000 feet, her opening five miles stand out as the strongest stretch of the race, averaging just under 10:00 per mile before the gradual late-race easing.
