Even Pacing Through Two-Thirds, Then a Late Fade Peter Mumaugh finished the marathon in 4:35:40, an overall pace of 10:31/mile. Through the first 20 miles he ran far more evenly than that final number suggests, holding splits mostly between 8:40 and 9:10. His strongest stretch came from mile 4 to mile 12, where he covered eight miles at roughly 8:46/mile. The final six miles told a different story, with several splits stretching past 14 and 15 minutes as he made his way toward downtown Boulder, pulling his overall pace down considerably from where it stood at halfway. This year's marathon course carried about 603 feet of net elevation gain, down from 982 feet previously a reduction reflected in the flat, controlled rhythm he sustained through the race's first two-thirds. Running at over 5,000 feet, that front-half pacing stands out even as the closing miles slowed.
