Steady Early Pace Gives Way to a Tougher Back Stretch Jeffrey Tan finished the marathon in 4:16:52, covering 26.2 miles at an overall pace of 9:48 per mile. Through the first eight miles he ran consistently between 8:43 and 9:07 per mile, holding elapsed pace right around 8:558:56 min/mile his most efficient stretch of the day. Splits stayed in a similar 8:559:32 range through mile 18, showing a well-controlled middle portion of the race. From mile 19 onward, per-mile splits shifted into the 10:5811:58 range, pulling his overall pace from 9:10 to 9:48 min/mile by the finish. Given that Boulder sits above 5,000 feet, sustaining sub-9:00 pace across the opening eight miles stands out as the strongest running of his race.
