Steady Pacing Powers a Top-5% Half Marathon Finish Jennifer Tsai crossed the line in 1:39:52, placing 351st overall out of the field of 7,223 and 69th among women. Her mile splits stayed remarkably tight through the first three miles at a 7:39 pace, then she found her strongest stretch between miles four and six, clicking off 7:20, 7:23, and 7:34 for her fastest three-mile stretch of the race. From there she settled back into a consistent low-7:30s to high-7:40s rhythm through the finish, showing strong control over the closing miles. Racing at Boulder's altitude of over 5,000 feet, Tsai's even effort across 13.1 miles reflects sound pacing discipline. Given how well she handled the middle miles, she might consider working on sustaining that same output through the final third for an even stronger finish next time.
