Strong Start Carries Steady Half-Marathon Finish Mark Sianipar completed the half marathon in 1:56:12, an 8:52 min/mile pace. He opened briskly, covering the first five miles in roughly 8:32-8:44 pace, then eased through the middle miles into the 8:47-9:07 range before a tougher patch through mile 11 at 9:36. He rallied over the final two miles, closing in 8:51 and 9:09 to finish strong. The opening five miles stood as his best sustained stretch, holding sub-8:45 pace throughout before the terrain and effort caught up with him. Through miles 9 and 10, he passed near the lululemon Power-Up Zone, posting a 9:02 mile in that stretch - a solid response before the race's most demanding mile that followed.
