Late Surge Powers Strong Marathon Finish Brendon Cassidy finished the marathon in 3:58:25, an average pace of 9:06 per mile across the 26.2-mile course. Cassidy ran steady mid-8:00s to low-9:00s miles through the first 18 miles before a slower 19th mile briefly loosened his rhythm. He responded well over miles 22 and 23, covering that stretch at roughly 8:20 per mile his fastest sustained running of the day before closing out the final miles in downtown Boulder. That surge came right around the lululemon Power-Up Zone near mile 22.5, and capped a race run at Boulder's altitude of over 5,000 feet.
