Steady Pace Powers a Top-25 Marathon Finish Bo Althen crossed the marathon line in 3:08:40, placing 25th overall and 20th among men in the field of 3,305, and finishing 3rd in the M30-34 division. After an opening mile at 7:01, he locked into a tight rhythm through the middle miles, holding between 6:52 and 7:18 per mile. The first ten miles were the standout stretch of the race, covered in 1:10:39 for a 7:04 average pace quicker than his overall 7:12 finishing pace. Splits eased slightly into the high 7:20s through the middle and later miles before he closed with a strong final mile at 7:00. That final surge, run at Boulder's altitude of over 5,000 feet, carried him to the finish on the historic Pearl Street Mall in downtown Boulder.
