Steady Pacing Carries Strong Closing Miles Kaiwen Song completed the half marathon in 1:42:15, holding remarkably even pace through the first ten miles, hovering between 7:53 and 8:00 min/mile for long stretches. The final three miles brought a clear shift, with splits of 7:57, 7:23, and 7:08, showing a strong finishing kick that pulled his overall elapsed pace down to 7:47 min/mile by the finish. That closing surge marked the fastest mile of the race, run from mile 12 to 13 at 7:08 min/mile a notable gear change after ten miles of disciplined, consistent effort. Along the way, Song passed through the lululemon Power-Up Zone near mile 9.5, covering that mile in 7:48, right in line with his overall rhythm. Given the steady middle miles, there may be room to test a slightly faster middle stretch in future races, letting the strong closing energy carry through more of the course.
