Strong Closing Miles Power a Top-Tier Marathon Finish Dazhen Gu ran 3:25:29 to finish 81st overall and 72nd among men in the 2026 Boulderthon Marathon, placing in the top 10% of the field of 3,305. His pacing held remarkably steady through the middle miles, holding between 7:57 and 8:01 per mile from mile 4 through mile 20, before dropping into a strong closing kick. The final four miles, from mile 22 to the finish, were his best stretch of the race, covering that distance at roughly 7:15 per mile well under his overall average pace of 7:50. That surge came right around the lululemon Power-Up Zone near mile 22.5, and carried him to a finish on the Pearl Street Mall in downtown Boulder, a city sitting above 5,000 feet of elevation.
