Strong Opening Miles Give Way to a Long Late-Race Fade Josh Epperson finished the 2026 Boulderthon Marathon in 5:40:51. His race showed a clear two-part shape: through the first 11 miles he held a steady 9:009:20 min/mile pace, reaching the halfway point near 2:05:47. From mile 12 onward, per-mile splits slowed steadily, stretching into the 1518 min/mile range through the back half and settling near a 13:00 min/mile pace for the full 26.2 miles. His strongest stretch came early miles 1 through 11 averaged roughly 9:09 per mile, the fastest sustained mile-plus segment of his day. Given that the course finishes on the Pearl Street Mall in downtown Boulder, sitting above 5,000 feet, that opening pace reflects strong early control. Working on maintaining more of that rhythm into the second half could help even out the pacing curve in a future race.
