Strong Front Half Gives Way to a Tough Closing Stretch Zachary Lamb crossed the finish in 4:37:41 for the marathon. Lamb's race unfolded in two distinct halves. Through the first 18 miles, he held a tight, controlled rhythm, running between 9:00 and 9:15 per mile and reaching that point in roughly 2:45:38 the most consistent stretch of his day. From mile 19 onward, the pace loosened considerably, with several miles slipping into the 1415 minute range before he rallied slightly over the final mile to close in 12:09. That closing stretch came after passing the lululemon Power-Up Zone near mile 22.5, a notable feature of the marathon course. Given the strength and steadiness of those opening 18 miles, building more of that early rhythm into the back half could be a worthwhile focus going forward.
