Steady Early Miles Carry a Strong Marathon Effort Jack Kardys crossed the finish in 4:16:59, averaging 9:48 per mile across the 26.2-mile marathon. His race built on a consistent opening stretch, holding between 9:13 and 9:20 per mile through the first eleven miles. His strongest sustained running came from miles 9 through 13, averaging roughly 9:04 per mile, before the pace eased over the closing miles as fatigue set in through the 20s. Running the marathon route out past Boulder Reservoir and along the county backroads before finishing on the Pearl Street Mall, Kardys covered the full distance at over 5,000 feet of elevation, a demanding backdrop for the steady early pace he carried through the race's midpoint.
