Steady Start Fades Into a Determined Finish Grace Growney completed the 10K at the 2026 Boulderthon in 1:02:04, an average pace of 10:00 per mile. Growney opened strong, clicking off her first mile in 9:15 and holding just above a 9:20 pace through the first three miles. From there, each successive mile slowed incrementally, with the final mile the day's toughest stretch as fatigue set in over the closing miles. Her first 3-mile block, completed in roughly 28:12, was the fastest sustained stretch of her racea pace worth revisiting as a benchmark for even splits next time. The race took place in Boulder, Colorado, sitting at over 5,000 feet of elevation, and finished on the historic Pearl Street Mall in downtown Boulder.
