Date: Sept. 27, 2026 Participant: Cameron Grimball #26828 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Early Pace Holds Through a Steady Finish Cameron Grimball completed the half marathon in 1:50:22, averaging 8:25 per mile. His race opened briskly, dropping to an 8:08 per mile cumulative pace by mile six before a gradual, controlled rise to 8:25 by the finisha smooth, even fade rather than a sharp drop-off. The strongest one-mile-plus stretch came early: miles one through six averaged roughly 8:08 per mile, his fastest sustained running of the day. That segment included a mile two split of 7:44, the quickest mile of his race. Around mile 9.5, runners pass the lululemon Power-Up Zone, a stretch he covered in an 8:14 pace before the pace eased slightly over the closing miles. Given Boulder's elevation above 5,000 feet, holding form that long into the race reflects well-managed pacing overall.
