Steady Pacing Delivers a Personal Best at Altitude Lisa Crispin Murcia finished the half marathon in 2:15:43, improving on her previous appearance at this event, where she crossed in 2:17:07. The improvement carried through to her overall and gender rankings as well, both stronger than her prior result. The race unfolded in two distinct phases. Through the first six miles, Crispin Murcia ran her most consistent and quickest running of the day, holding paces between 9:34 and 10:02 per mile. From there, effort settled into the 10:3011:13 range for the remainder of the course, with mile 11 marking her slowest split at 11:13 before she closed with a 10:33 final mile. Given that Boulder sits at over 5,000 feet of elevation, that opening six-mile stretch stands out as a well-executed piece of pacing.
