Steady Pace Holds Through Midrace Before Late Miles Cost Time Collin Child finished the Boulderthon Marathon in 4:10:25, an overall elapsed pace of 9:33 per mile. His race stayed remarkably consistent through the middle miles, holding between 9:12 and 9:43 per mile from mile 1 through mile 19, with a strong mile 11 split of 8:32. From mile 20 onward, pace eased into the 10:0610:17 range, nudging his cumulative pace from 9:24 at mile 20 up to 9:34 by the finish. The strongest stretch came from mile 15 through mile 19, averaging roughly 9:17 per mile, the most efficient multi-mile segment of his race. Running that pace across Boulder's roads, which sit above 5,000 feet of elevation, reflects well on his pacing discipline through the bulk of the distance. A touch more reserve for the closing miles could help him carry that mid-race rhythm all the way to the Pearl Street Mall finish next time.
