Steady Early Pace Gives Way to a Tough Back Half Jack Curtis finished the marathon in 4:08:25, an overall elapsed pace of 9:28 per mile. The race unfolded in two distinct halves: through the first 13 miles, Curtis moved briskly and evenly, crossing the half in 1:49:03 with a cumulative pace holding near 8:23 per mile. From mile 14 onward, the pace steadily slipped, climbing past 9:00 by mile 21 and settling into the 10:3012:40 range for several late miles before a final push brought him home. That opening 13-mile stretch stands out as the strongest running of the day, tight and controlled mile after mile in the 8:10-to-8:52 range. Holding that rhythm at Boulder's altitude, above 5,000 feet, made for a strong foundation before the closing miles caught up with him. Finishing on the Pearl Street Mall capped the effort in downtown Boulder.
