Steady Early Pace Gives Way to a Tough Final Stretch Oscar Golberg finished the 2026 Boulderthon Marathon in 4:23:09, averaging 10:02 min/mile over the 26.2-mile course. Golberg ran the first 20 miles with notable consistency, holding a cumulative pace between 8:59 and 9:12 min/mile through mile 20. His strongest mile-plus stretch came between miles 10 and 13, where he covered three miles in roughly 25 minutes, dipping to an 8:05 split at mile 11. The final 10K told a different story, as his pace slowed considerably from mile 21 onward, with splits climbing into the 13- and 14-minute range before a rebound to 10:13 for the last mile. Given Boulder's elevation above 5,000 feet, the early-race pace management set a solid foundation, even as the closing miles proved demanding.
